Summarize any observations hat you think are significant and could help you explain or support your results. The lab may or may not specifically direct you to make observations,

Purpose and Hypothesis

This section should be a concise summary of the lab .
State the purpose, the main scientific ideas/concepts you are trying to learn about or prove/observe .
State your hypothesis: focus on the science, NOT the learning objectives. This should be a prediction in the form of a clear, confident statement regarding what you would expect to happen in your experiment.

Pre‐Lab Questions

Most labs have pre‐lab questions associated with them.  copy the questions into your report and answer them in complete sentences, explaining your answers. The example questions shown at the end of this document also apply to the pre‐lab questions.

This section should briefly summarize what you did. NOTE: This section is where you want to place your photos for your lab.

Data: Clearly present your data. Include data tables and graphs . While graphs may not be needed for every lab, data tables usually are. If you list numbers, make sure units are either with all the numbers or make sure the column label includes the appropriate unit associated with all the numbers in that column.
Observations: Write in past tense. Here you summarize any observations hat you think are significant and could help you explain or support your results. The lab may or may not specifically direct you to make observations, however in either case you should include a few general observations from the experiment which are not directly reported in your data tables.

Why does the protein product stay the same after some point mutations, but change after others?

Simulate 3 different point mutations, 3 different insertion mutations, and 3 different deletion mutations starting from the original sequence of amino acids and explain why the protein product stays the same after some point mutations, but changes after others. Take pictures of the screen for all nine mutations and insert them below. Describe the mutation and explain the effect on the peptide.

Point mutation 1

Point mutation 2

Point mutation 3

Insertion mutation 1

Insertion mutation 2

Insertion mutation 3

Deletion mutation 1

Deletion mutation 2

Deletion mutation 3

Activity 5

Step 1: Design a protein product that consists of mainly hydrophilic amino acids. Take pictures of the screen and insert them on the lab manual template.

Step 2: In order for a protein to be exported out of the cell, the head needs to be hydrophobic. Design a protein with a hydrophobic head of at least four amino acids. Take pictures of the screen in the simulation of the protein you have designed and insert them on the lab manual template.

Why does the protein product stay the same after some point mutations, but change after others?

Summarize in detail the main findings of the lab. Your conclusion should be one paragraph and on the order of 4 – 5 sentences. Summarize the main results and conclusions from the experiment and the main sources of error.

This section needs to show calculations for any calculations that were needed in regarding your data.
You must show work for the calculations in the questions or you will not get credit for you answer.

Conclusion
This section should summarize in detail the main findings of the lab. Your conclusion should be one paragraph and on the order of 4 – 5 sentences. Summarize the main results and conclusions from the experiment and the main sources of error. You may also include what you learned in the experiment or any results that you found surprising. For example:
State at least three sources of error in the lab.
Sources of error do NOT include errors in calculations. Do not say “human error”.
Error is classified as random or systematic, with explanations.
Find things within the lab that you could not control this time, but that you might be able to control if you could repeat the experiment under different conditions or with better equipment. Do not list things like not reading the directions, not cleaning glassware, or just being careless.

How well does this regression analysis explain the ratings? Should the executives count on the results from this analysis? Justify your answers referring to the relevant figures.

Your answer should include the following:
a) The null and alternative hypotheses .
b)The test results: Run the test using Excel and include the output table. Use a t-test assuming equal variances.
c)What is your recommendation to the executives? Justify your answer referring to the relevant figures.
5) Run a multiple regression where the dependent variable is ratings and the independent variables are star and fact. Use data from CBC only. CBC Management has several questions:
a)Executives wish to know how much being fact-based or having one star contributes to a movies rating. What can you tell them about this?
b)Are either, both, or neither of the independent variables significantly related to the ratings at 95% confidence? Justify your answers referring to the relevant figures.
c)How well does this regression analysis explain the ratings? Should the executives count on the results from this analysis? Justify your answers referring to the relevant figures.

What is the average rating for all CBC movies? How about ABN movies and BBS movies? Provide a bar chart that compares these averages.

You will be analyzing the “Colonial Broadcasting” case included with the course pack that you bought at the beginning of the course . Begin by reading the description in the case. Then, answer the questions listed below, NOT the questions listed in the case. Ignore everything in the case document after the end of page 4.

The executives at CBC have four main areas in which they are interested: They want to see how they are doing in ratings against the other networks and how the ratings will continue to change in the upcoming months. They also want to know if hiring stars makes a difference and the impact of fact-based programming compared to hiring stars.

Remember that your audience is the management of CBC. Therefore, make sure your presentation is professional. Once you present your results, you need to justify and explain your findings with properly stated conclusions.

1) Answer the following questions:

a) What is the average rating for all CBC movies? How about ABN movies and BBS movies? Provide a bar chart that compares these averages.
b) Include a table that shows the descriptive statistics using the data analysis tool pack in Excel for the ratings of the three networks .
c) Comment on how the networks are performing, by comparing and interpreting the metrics in the descriptive statistics table. Your analysis must extend beyond simply comparing the average ratings for each network.
2) Create a line graph of the monthly average ratings for CBC for the year. Note that there are multiple ratings data for the months; you will need to calculate an average for each month first, and then plot the averages. After you create the graph, fit a linear trend line and a 2nd order polynomial trend line, displaying the formula and the r-squared. Explain to the executives if you can use this time series data to forecast the ratings of upcoming months. Which forecasting method is better? How accurate can you expect this forecast to be?

Why do you consider them the most innovative works? What about them is innovative?

In a 3 page essay, discuss, from your readings, what you consider the three most innovative artworks or buildings from the Prehistoric Period through the Late Gothic / Proto-Renaissance Period . Your three choices must come from the course textbook and the works we studied in class. You can choose any work from your Homework lists.

Answer the following questions in a well crafted essay .

1) Why do you consider them the most innovative works? What about them is innovative?

2) How did they influence later artists? Who were the later artists that they influenced?

Describe and explain each of your choices fully . Include specific artists, titles, dates and styles, and use terms from your textbook to illustrate your points.
