1. Jenny wants to know which college among the 3 she has attended that is best. In fact, she visited each school this past week. To answer her question, she asked five people at each school to rate how awesome their school is on a scale from 1 to 20, with 20 being the most awesome score possible. The results are below.

a. State the null and alternative hypotheses.

b. Conduct an ANOVA, showing all your work for each step, and then also report your answers in an ANOVA table like the one below. You need to show both the work for the answers you will present in the table and then also present the completed table itself.

c. Use a Type I error rate of α (alpha) = 0.05, look up your critical F-value.

d. What do you conclude regarding the null hypothesis? Would the p-value be bigger or smaller than alpha?

e. What do you conclude about your research question (use your own words, in everyday language)?

f. Conduct and interpret follow-up t-tests for this ANOVA analysis, including an overall interpretation of the results.

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 61 students enrolled in those two courses. Data concerning the company’s cost formulas appear below:

For example, administrative expenses should be $3,600 per month plus $46 per course plus $7 per student. The company’s sales should average $890 per student.

The company planned to run four courses with a total of 61 students; however, it actually ran four courses with a total of only 57 students. The actual operating results for September appear below:

Required:

1. Prepare the company’s planning budget for September.

2. Prepare the company’s flexible budget for September.

3. Calculate the revenue and spending variances for September.

Case Studies: For each of the following scenarios, give a brief explanation of what you would suggest, and why.

You are working as a Nurse at a rural high school and have been asked to assess the body composition and overall health of the students. What specific body composition assessment technique would you use (consider price, ease of use, etc…)? Make sure you explain why you would choose this technique. (3 pts)

You have been asked to give a presentation to elementary school students at a local school. They are having a health fair and want you to speak about nutrition and health – with a specific emphasis on teaching healthy eating habits to help avoid childhood obesity. List 3 things you would say to the students. (I don’t want words repeated from the Powerpoint or book, I am looking for creative and well thought out pieces of advice! Also, remember that your answers should be appropriate and relatable to your audience. (3 pts)

You are opening up a restaurant here in Albany. You want to promote healthy eating, but also want to make a profit (so the food has to taste good and include things that will bring people in!). Give examples of foods you would put on the menu to try to achieve this, and list why you chose each food. Be specific in your menu items (portion size, all things included in each dish, etc…):

TipTop Flight School offers flying lessons at a small municipal airport. The school’s owner and manager has been attempting to evaluate performance and control costs using a variance report that compares the planning budget to actual results. A recent variance report appears below:

After several months of using such variance reports, the owner has become frustrated. For example, she is quite confident that instructor wages were very tightly controlled in July, but the report shows an unfavorable variance.

The planning budget was developed using the following formulas, where q is the number of lessons sold:

2. Complete the flexible budget performance report for the school for July.

5. Doogie lives for four periods. He has just completed the first period of his life (by getting his high school diploma). Doogie is trying to decide on his future career path. He’s very good at opening things up and fixing them, so he has narrowed his options to two possible paths. He will either become an auto mechanic or a brain surgeon. •If Doogie becomes an auto mechanic, he will earn $25,000 as an apprentice in period 2, $50,000 as a solo mechanic in period 3, and $75,000 as a master mechanic (with apprentice) in period 4. •If Doogie becomes a brain surgeon, he will pay $50,000 to attend college in period 2, another $75,000 to attend medical school in period 3, and will earn $300,000 in period 4. Doogie must make all tuition payments at the beginning of each period, he is paid at the end of every period, and he can borrow and lend at a rate of 8% per period.

a. What is the present discounted value (PDV) of Doogie’s possible career paths? If Doogie wants to maximize the PDV of his lifetime earnings, which career should he choose?

b. Would Doogie’s choice change if he was making his decision at birth? Would the PDV (present discounted value) of his earnings streams be different at birth? Would Doogie’s evaluation of this investment change if he started life with a trust fund of $1 million? Explain. (Assume that Doogie’s high school education in period 1 is necessary for both career paths and is costless.)

A sample of 449 government employees and some number of respondents from private corporations answered the question about their education in 2018. Compare their average highest year of school completed and answer the question: Did government employees on average have more education than private employees in the U.S. in 2018? Explain why you think so. [Do not run the test in SPSS. Use the SPSS output below.]

T-Test

1. Calculate the values to put into two blanks (----). [See the output above].

2. State the null hypothesis (in words).

3. State the research (one-tailed) hypothesis (in words). [Hint: inspect the sample means for stating correct direction].

4. Find t_critical for one-tailed test.

an 18-year-old male high school student who had a 4-year history of diabetes mellitus was brought ... Question: An 18-year-old male high school student who had a 4-year history of diabetes mellitus was brought... An 18-year-old male high school student who had a 4-year history of diabetes mellitus was brought to the emergency department because of excessive drowsiness, vomiting, and diarrhea. His diabetes had been well controlled with 40 units of NPH insulin daily until several days ago when he developed excessive thirst and polyuria. For the past 3 days, he has also had headaches, myalgia, and a low-grade fever. Diarrhea and vomiting began 1 day ago. URINALYSIS RESULTS and CHEMISTRY TEST RESULTS
