College students were asked to rate the spring festivals at university in years 2016, 2017, and 2018. The following table shows the students’ ratings on a scale from 0 to 100 where larger values are assigned to better activities. Construct an ANOVA table and determine whether there is a significant difference among the student appreciation of spring festivals for different years. Assume a significance level of α = 0.05.

A recent headline announced / impeachment causes a dip in a President’s Approval Rating.
This conclusion was based on a University poll of 100 adults. In the poll, 41.1% of respondents approved of the president’s job performance.

(a) Based on this poll, what is the probability that more than 50% of the population approve of the president’s job performance?
(b) Form a 90% confidence interval for this estimate.

(c) Assume we know without sampling error the population support was 42% before the impeachment story broke in September. Test whether the impeachment proceedings have actually caused a dip in approval from the 42% baseline at the .05 significance level.

A consultant for a large university studied the number of hours per week freshmen watch TV versus the number of hours seniors do. The result of this study follow. Is there enough evidence to show the mean number of hours per week freshman watch TV is different from the mean number of hours seniors do at alpha= 0.01?

For the Hypothesis stated above (in terms of Seniors- Freshmen)

What are the critical values?

What is the decision?

What is the p-value? (Round off to 4 decimal place)

Problem #1 -- Historically, 20% of graduates of the engineering school at a major university have been women. In a recent, randomly selected graduating class of 210 students, 58 were females. Does the sample data present convincing evidence that the proportion of female graduates from the engineering school has shifted (changed)? Use α = 0.05.

A. Explain what it means to make a Type I error and indicate the probability of it occurring, under the assumption the null hypothesis was true.

B. Explain what it means to make a Type II error and suggest a possible value of the parameter in order for such an error to occur.

1.

Scott is a self-employed plumber and his wife, Emily, is a full-time employee for a University. Emily has health insurance from a qualified plan provided by the University, but Scott has chosen to purchase his own health insurance rather than participate in Emily's plan. Besides paying $5,590 for his health insurance premiums, Scott also pays the following expenses associated with his plumbing business:

Plumbing tools and supplies       $1,490​

Rent on Scott's plumbing shop   6,440​

Transportation between Scott's shop and various jobsites            690​

Plumber's uniform          70​

Plumbing truck rental    7,390​

Total self-employment tax          590​

What is the amount of deductions for AGI that Scott can claim this year (2019)?

This year, Benjamin Hassell paid $15,600 of interest on a mortgage on his home (Benjamin borrowed $520,000 in 2015 to buy the residence and it is currently worth $832,000), $11,200 on a $140,000 home-equity loan on his home, and $9,750 of interest on a mortgage on his vacation home (loan of $325,000; home purchased for $425,000 in 2016; home is not rented out at any time). How much interest expense can Benjamin deduct as an itemized deduction?

1. The Barry family had two sons in college at the same time. Their parents gave both boys an allowance for food and textbooks. For simplicity, assume Drew and Brent have identical preferences between food and textbooks and that both are normal goods. Drew went to Georgia Tech University (GT), while Brent went to Oregon State University (OSU), where food prices were higher. Both boys bought their textbooks from an online store with free shipping and no tax, so they paid the same price for textbooks.

1. Using indifference curves and budget constraints, show the choices of Drew and Brent if the Barrys gave the boys the same allowance.
2. You might expect that Brent would be a little annoyed at the situation. Suppose he calls up his parents and convinces them that they need to give him more money to compensate him for the fact that food is so much more expensive in Oregon. His call is successful, and his parents agree to give him more money. Brent wants enough to buy the same bundle the Drew buys. Always wanting to treat their kids fairly, Brent’s parents instead give Brent enough money to be just as happy as Drew is (i.e., on the same indifference curve). Show this new budget constraint and Brent’s utility-maximizing choice of food and books.
3. Explain how your answer to the previous question help illustrate the income and substitution effects of a price change from Georgia’s low food prices to Oregon’s high food prices.

1. A grocery store gave people the choice for a free sample of chocolate-chip brownies or chocolate-chip cake. They were told they were only allowed to pick one of the two samples and their choices were recorded.The statistic observers ensured that the samples were plentiful to prevent people from feeling bad for taking all of one sample or the other. Over the course of 325 customers, 210 chose the chocolate-chip brownies.

a) Can we perform a statistical study based on this sample?

b) Create a Hypothesis Test for the importance of chocolate-chip brownies over cake.

c) Estimate the standard error for this study. Round to three decimal places.

d) Find the test statistic for your study. Round to three decimal places.

e) Find the p-value.

f) Do we have enough evidence that people prefer chocolate-chip brownies over cake?

2.  A community university wants to suggest its students have all scored over 500 on their SAT English scores each year. Gathering 40 random students from the past 10 years, the average score per year is 520 with a standard deviation of 110.

a) Is this sample appropriate for a normalized confidence interval?

b) Find the standard error for this sample.

c) Find the appropriate t-distribution for the 95% confidence interval.

d) Find the confidence interval based on the sample.

e) Based on your confidence interval, is the university allowed to brag about its high SAT English scores?  Why or why not?
