Homework1

1. You will submit your HW assignment within Canvas in the Assignments area. Remember to use naming convention detailed in the syllabus. Word, Excel, screenshots, .jpegs, .pdfs &/or all types of documents can be submitted.

2. Please include a cover sheet with your name and date, that includes online submissions.

3. Include a short synopsis of the problem, all assumptions, and definitions used at the beginning of each exercise.

4. Answer the problems as completely as possible. Neatness, accuracy, and overall clarity of work are important. Full credit will only be given for problems, which include the aforementioned items. I am looking for process and methodology not necessarily one correct answer.

Remember: You are telling a "story" in the attempt to win a contract from a client, do your best to tell the story, win the contract, and get paid (or in this case get an excellent grade!)

The same instructions apply for all homework problems. It is vitally important that you do a good job defining the problem, stating assumptions, explaining your analysis, feel free to use graphs, tables, and/or any other means to get your point across. Simply writing an answer down is woefully inadequate (i.e., you will receive no points).

1. Construct a stem and leaf plot for the following data:

NOTE: There are two columns of data & use the tens place of the scores as your stems, e.g., for numbers less than 20 use the 1 of 10, for numbers between 20 and 30 use the 2 of 20 etc.

Scores	Scores
30	28
31	18
35	55
40	26
45	49
41	51
25	32

Compare this stem and leaf plot to the plot you created in question 1.

3. Construct a histogram for question 1 and question 2. Use below 20, 20-30, 31-40, 41-50, and above 50 as your bins with the actual bin values as 10, 20, 30, 40, & 50. What can we tell about the two data sets from the two histograms?

e. Compare the two sets of descriptive statistics & comment on similarities or differences
