Researchers are interested in comparing the depression scores (measured on a scale of 1-100) of patients diagnosed with clinical depression before and after they have participated in a new exercise regimen. They take a random sample of 5 people who report low levels of exercise and measure their depression scores. They then have these 5 patients complete a 4-week exercise regimen and measure their depression scores after the 4 weeks. Results of analysis are presented in the table below.

Your research question of interest is:

Is there a difference in the mean depression score of patients before and after they participate in the 4- week exercise regimen?

You are informed the estimated standard error of the mean differences (s) is 1.74

You will use the information above to complete the question parts below for a two related samples t-test.

Part A: Which of the following represents the appropriate null hypothesis (H₀), given this research question of interest?

Part B: Which of the following represents the appropriate alternative hypothesis (H₁), given this research question of interest?

Part C: Which of the following represents the appropriate critical value(s), testing at an alpha level (α) of 0.05?

Part D: What is the t-statistic associated with your test? (rounded to the nearest hundredth) - see note above for the value of the standard error of the mean differences.

Part E: Given your test results, what is your decision about the null hypothesis?

Part F: The best interpretation of the appropriate decision regarding the null hypothesis would be: "Based on our study, we (Have/Have not)

enough evidence to conclude that there appears to be a difference in the population mean depression score before and after a 4 week exercise regimen."

(g) In one factual sentence, state what information your answer for the inflation rate in (f) above tells us. I do not want an opinion as to whether this number is high or low. Please use your answer in (f) above in your answer for (g).

(h) If Sue lent Bill $20,000 at the start of 2010 for 1 year and charged Bill a nominal interest rate of 12.00%, then please calculate the real interest rate that Sue earned for this 1 year loan. Please show how you got your answer. Please be clear what your answer is and calculate your answer to the second decimal place (hundredths place).

(i) If Sue wanted to earn a real interest rate (return) of 12.00% for the loan mentioned in (h) above, then what nominal interest rate should she have charged Bill? Please show how you got your answer. Please be clear what your answer is and calculate your answer to the second decimal place (hundredths place)

1) Create a dictionary containing the following pieces of information about a student:
Her name is Emmylou; She is on track to graduate in Fall 2021; Her bill is paid; Her major is Archeology; She belongs to these school clubs – Photography, Acting and Glee

(Your job as the programmer is to choose the best data type as well as any key names you will use within the program)

2) Do the same for another student:
His name is Javier; He is on track to graduate in Spring 2021; His bill is unpaid; His major is Math; He belongs to these school clubs – Archery and Acting

3) Create a list whose contents is the dictionaries you created in step 1 & 2.

Write a java program that calculates the total amount of money a person has made over the last year. The program will prompt the user for dollar amounts showing how much the user has made per job. Some users will have had more than one job, make sure your program allows for this. The program will print out the total made (all jobs) and will print out the federal and state taxes based on the total made. For this program, the federal tax will be 8.5% and the state tax will be 14.5%.

1. Use appropriate comments throughout the program. ***PLEASE BE AS DETAILED AS POSSIBLE TO UNDERSTAND CODE FORMAT***
2. Create a header at the top showing the programmer, date of creation and class.
3. Make sure you insert appropriate instructions for the user.
