2 large retail companies (W and T) are compared on a Census variable, percent of people who own their home within 3 square miles of the store. The percent that own their home for W is:
84, 79, 73, 81, 74, 77, 64, 78, 78, 78, 61
Percent for T is:
58, 61, 57, 62, 61, 59, 56, 64, 61, 70.
- Estimate the difference in percent owning their home for the two companies as to central tendency using lambda=.05. In estimating the difference, use 1 parametric approach, 1 robust(trimming) or nonparametric approach, and the best bootstrapping approach(not jackknife). Make a case for which approach is best.

On January 1, 2013, an investor bought 300 shares of Gottahavit, Inc., for $69 per share. On January 3, 2014, the investor sold the stock for $74 per share. The stock paid a quarterly dividend of $0.24 per share. How much(in $) did the investor earn on this investment and, assuming the investor is in the 33% tax bracket, how much will she pay in income taxes on this transaction? Assume a preferential tax rate of 15% on dividends and capital gains.
A)The amount (before taxes) the investor earned on this investment is $______ (Round to the nearest dollar.)
B)Assuming a preferential tax rate of 15%, the amount she will pay in income taxes on this transaction is $_____.(Round to the nearest cent.)

The data below are the final exam scores of 10 randomly selected calculus students and the number of hours they slept the night before the exam:
| Hours Slept (x) | 7 | 11 | 6 | 13 | 7 | 8 | 8 | 11 | 12 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|
| Exam Scores (y) | 68 | 83 | 63 | 91 | 69 | 81 | 88 | 93 | 93 | 74 |
Using the equation of the regression line, with all numbers in it rounded to 2 decimal places, predict the final exam score of a student who slept for 3 hours the night before the exam. (Round the score to 2 decimal places)

John wishes to study the heights of the women’s basketball team.
He completes a simple random sample of women’s basketball team
members. 70 71 69.25 68.5 69 70 71 70 70 69.5 74
75.5
John knows that women’s heights are normally distributed. Use the
critical value method and a 5% significance level to test the claim
that women’s basketball players have heights with a mean greater
than 68.6 inches (population mean height of men).
1) What is the significance level ?
2) What is the critical value?
3) What is the test statistic?
4) What is the statistical conclusion? (Reject or Fail to Reject

Your local hotel has a dining room which has the capacity to seat 140 guests. It is opened for breakfast and lunch seven days a week and fully expects to be at capacity at these times. During January 2021, management has forecast the seat turnover for breakfast will be 3 times and for lunch 2 times, with the average bill to be $28 for breakfast and $58 for lunch. Beverage revenue is usually 12 per cent of the breakfast revenue and 28 per cent of the lunch revenue.
Calculate budgeted total revenue of food and beverage for the 31 days of January 2021. Express the answer as a daily food and beverage outcome and also a monthly figure.

What are the mean school performance scores for the superintendent’s district and matched schools? 2. What are the standard deviations of the school performance scores for the superintendent’s district and matched schools? 3. State an appropriate null hypothesis for this analysis. 4. What is the observed or computed value of t? 5. What is the value of the degrees of freedom that are reported in the output? 6. What is the reported level of significance from the T Test for Dependent Means? 7. Based on the results of the T Test for Dependent Means, what would you conclude about the difference in scores of schools in the superintendent’s district and the matched schools? 8. Present the results as they might appear in an article. This must include a table and narrative statement that reports the results of the T Test for Dependent Means.
