Prof Rea’s Exam Question 4. Show as much work as possible and clearly show all four steps of a hypothesis test to earn credit: Last year, researchers determined that the average cost for health insurance for an individual in the US was $605 per month. You wonder if the average monthly cost for health insurance has decreased since last year. You randomly survey 125 adults in the US and find that they spend an average of $585 per month on health insurance. You compute the sample standard deviation to be $82. Test your claim using a 5% level of significance. Include your desmos formulas/work and show your thinking on the provided graph*. Round all calculated values to three decimal places. *No credit will be awarded for this problem if these items are missing from uploaded work.

1. This assessment is enabling you to demonstrate your understanding of the concepts presented in unit 7, and section 8.1. Use techniques you have learned to solve the problems on the assessment. Points will be earned primarily through the process of solving. Therefore, you will show as much work as possible and will provide justification whenever necessary. Write your favorite color on the bottom of the first page for an extra point. Use models, tables, and/or write descriptively when providing explanations.  The solutions you provide should be of your own original thought. Collaboration/discussion with anyone, including searching online or the use of any AI program, is not permitted. desmos graphing and scientific calculators are permitted on this assessment, but you will be required to show how you reached your answers (especially if the directions say “show the calculation to earn credit”). Please indicate which function in desmos you used to find probabilities and/or critical values and/or sample means/standard deviations. If I suspect any part of the work is not your own, you will earn a zero on  the assessment and the activity will be reported to the college to be formally processed and permanently recorded.  Sign your name on your work and answer template to acknowledge and agree to these terms. 

Prof Rea’s Exam Question 2. A restaurant is deciding which farm to order berries from for a seasonal dessert on their menu. The average cost for a pound of berries in California is $2.82 with a population standard deviation of $0.45. Assume that berry cost in California is normally distributed. Suppose that farms in California sell 10 different kinds of berries.  Explain why the sampling distribution of sample means is approximately normal.  Find the mean,

Prof Rea’s Exam Q8 Given below is a scatterplot that shows the number of Computer Science doctorates awarded in the US and arcade revenue per year (in billions of dollars).  The equation of the line of best fit is

You need to generate invoice numbers for even-numbered clients, starting at 1000 and going up to (but not including) 1010. What output will this code produce? for client in range(1000, 1010, 2):     print(client) 1000, 1001, 1002, …, 1009B. 1000, 1002, 1004, 1006, 1008C. 1000, 1002, 1004, 1006, 1008, 1010D. 1002, 1004, 1006, 1008 Answer: B Explanation:This range(start, stop, step) includes the start (1000) and goes up to but not including 1010, stepping by 2. A and C include invalid values for the given step and bounds. D starts at 1002, which is incorrect.

You loop through a list of coupon codes. Skip the expired code “DISC0” and stop processing once you hit the “FINAL” flag.How many codes are printed by this loop? python CopyEdit codes = [‘DISC10’, ‘DISC0’, ‘DISC20’, ‘FINAL’, ‘DISC30’] for code in codes:     if code == ‘DISC0’:         continue     if code == ‘FINAL’:         break     print(code) Answer: 2 Explanation: “DISC10” is printed “DISC0” is skipped due to continue “DISC20” is printed “FINAL” triggers the break, stopping before printing “DISC30” is never reached

A coordinator needs to contact every 3rd vendor in a list of 30. If vendors are numbered from 1 to 30, which code correctly selects vendor numbers: 1, 4, 7, …? for vendor in range(1, 31, 3): print(vendor)B. for vendor in range(3, 30): print(vendor)C. for vendor in vendors: if vendor % 3 == 0: print(vendor)D. for vendor in range(0, 30, 3): print(vendor + 1) Answer: A Explanation:Option A begins at 1 and increments by 3, selecting every third vendor. B starts at 3, not 1 C selects vendors divisible by 3, not every third D would work but outputs 1, 4, 7… using an offset; A is clearer and more direct.
