In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.

Suppose that at five weather stations on Trail Ridge Road in Rocky Mountain National Park, the peak wind gusts (in miles per hour) for January and April are recorded below.

Does this information indicate that the peak wind gusts are higher in January than in April? Use α = 0.01. Solve the problem using the critical region method of testing. (Let d = January − April. Round your answers to three decimal places.)

In early March, 2020, our state government announced tentative plans to move homeless people in to college dorm rooms. A. In your opinion, is this idea a good idea? Or a bad idea? Why? B. Would you make this program voluntary for homeless people? Or mandatory? Why? C. How vigorously would you enforce this program? Why? D. What penalties, if any, would you impose on homeless people for non-compliance? Why? E. In theory, what could ‘go wrong’ with the enforcement of this program? What other support services do homeless people require, in addition to housing? F. Moving homeless people into hotel rooms, (combined with support services), which our state has done on an unprecedented level, may be a better idea than moving them into college dorms. Why? G. In your opinion, what more should we be doing as a society to address this issue? Why?

1. One investing firm is assessing an opportunity of a real estate investment. The project requires 4.5 million CAD at the beginning of the first year to start up the first complex and 1.6 million CAD at the beginning of the second year to start the second complex. Upon completion in two years, a hotel industry customer would purchase the whole project for 8.7 million CAD. If the average secure interest rate from a bank is 4%, determine the return rate of the investment.

2. One investor wants to buy an apartment for 370,000 CAD. He then wants to rent his property for 1700 CAD a month for a year and after the year sell it for 475,000 CAD. The bank guaranteed him a return rate of 3% per annum through a mutual fund investment that can be calculated monthly. This means the investor can invest the rent money in the bank. The investor wants to know what the return rate of this investment is.

Clive Palmer treated Queensland Nickel as $200m

Piggy BankClive Palmer is accused of being a reckless, shadow company director who took$200 million out of a Queensland nickel company to fund his political party andinvestments, including a new Titanic.

Administrators of Queensland Nickel, which closed last month, said yesterday thecompany was used as a “piggy bank” to finance what they termed the “Palmerempire”.

More than $200 million was taken out of the company over a five-year period andpumped into companies that were directly related to Mr Palmer, including hisflagship business Mineralogy, FTI Consulting said in its report.

But John Park, from FTI, said his investigations found $189 million in loans tocompanies linked to Mr Palmer were “forgiven” or not paid back to QueenslandNickel, including $5.9 million that went into the plans for the Titanic II.

Of the money that went into the Titanic, most was spent on lavish launch partieswith the only assets now some intellectual property and a “plastic boat”.

The company also became the single biggest political donor in the country,delivering $21.5 million to the Palmer United Party.

The administrators said Queensland Nickel accounted for 27 per cent of thenation’s total political donations in 2014 and last year, including the WA Senateby-election when Palmer United’s Dio Wang was elected.

While money was flowing out of the nickel company into the Palmer CoolumResort and other firms, the world nickel price was falling.

Mr Park said the borrowing from the company could have continued if nickelprices remained high.

“At a very high level, we saw Queensland Nickel as what I’d say (was) the piggybank, the treasury,” Mr Park said.

“And the money was coming through Queensland Nickel in the better times and itwas being dissipated amongst the Palmer empire entities.”

Up to 800 workers are owed $74 million in entitlements.

They are likely to get most of those entitlements paid out under a FederalGovernment program. Remaining creditors will likely get between nothing and 50¢for every dollar owed.

The administrators believe Mr Palmer and his nephew Clive Mensink, QueenslandNickel’s sole director, should be examined by the Australian Securities andInvestments Commission.

They claimed Mr Palmer acted as “shadow director” and that he and Mr Mensinkhad been “reckless in exercising their duties and powers as directors” for takingactions not in the interests of Queensland Nickel.

Mr Palmer is planning to fight any action and argued he was being singled outwhen Prime Minister Malcolm Turnbull was standing by as jobs disappeared in Queensland.

“Despite me controlling a lot of things, being Dr Evil, if you like, I don’t controlthe world’s international nickel price,” he told Melbourne radio.

Mr Palmer said there was a witch-hunt against him for making decisions that hewas entitled to make.

“I mean, that's my money. That's what we live in - a free society, and people havethe right to spend their money as they see fit,” he told the Seven Network.

Mr Palmer is the sole shareholder of Queensland Nickel. His nephew Mr Mensink isthe sole company director. The Administrators believe that Mr Palmer should beexamined by ASIC for breach of s184 of the Corporations Act.

Do you think ASIC would be successful in charging Mr. Palmer for breach of s184of the Corporations Act?

We need to find the confidence interval for the SLEEP variable. To do this, we need to find the mean and standard deviation with the Week 1 spreadsheet. Then we can the Week 5 spreadsheet to find the confidence interval.

First, find the mean and standard deviation by copying the SLEEP variable and pasting it into the Week 1 spreadsheet. Write down the mean and the sample standard deviation as well as the count. Open the Week 5 spreadsheet and type in the values needed in the green cells at the top. The confidence interval is shown in the yellow cells as the lower limit and the upper limit.

1. Give and interpret the 95% confidence interval for the hours of sleep a student gets. Change the confidence level to 99% to find the 99% confidence interval for the SLEEP variable.

2. Give and interpret the 99% confidence interval for the hours of sleep a student gets.

3. Compare the 95% and 99% confidence intervals for the hours of sleep a student gets. Explain the difference between these intervals and why this difference occurs.

In the Week 2 Lab, you found the mean and the standard deviation for the HEIGHT variable for both males and females. Use those values for follow these directions to calculate the numbers again.

(From Week 2 Lab: Calculate descriptive statistics for the variable Height by Gender. Click on Insert and then Pivot Table. Click in the top box and select all the data (including labels) from Height through Gender. Also click on “new worksheet” and then OK. On the right of the new sheet, click on Height and Gender, making sure that Gender is in the Rows box and Height is in the Values box. Click on the down arrow next to Height in the Values box and select Value Field Settings. In the pop up box, click Average then OK. Write these down.

Then click on the down arrow next to Height in the Values box again and select Value Field Settings. In the pop up box, click on StdDev then OK. Write these values down.)

You will also need the number of males and the number of females in the dataset. You can either use the same pivot table created above by selecting Count in the Value Field Settings, or you can actually count in the dataset. Then use the Week 5 spreadsheet to calculate the following confidence intervals. The male confidence interval would be one calculation in the spreadsheet and the females would be a second calculation.

4. Give and interpret the 95% confidence intervals for males and females on the HEIGHT variable. Which is wider and why?

5. Give and interpret the 99% confidence intervals for males and females on the HEIGHT variable. Which is wider and why?

6. Find the mean and standard deviation of the DRIVE variable by copying that variable into the Week 1 spreadsheet. Use the Week 4 spreadsheet to determine the percentage of data points from that data set that we would expect to be less than 40. To find the actual percentage in the dataset, sort the DRIVE variable and count how many of the data points are less than 40 out of the total 35 data points. That is the actual percentage. How does this compare with your prediction? Mean ______________ Standard deviation ____________________ Predicted percentage ______________________________ Actual percentage _____________________________ Comparison ___________________________________________________ ______________________________________________________________

7. What percentage of data would you predict would be between 40 and 70 and what percentage would you predict would be more than 70 miles? Use the Week 4 spreadsheet again to find the percentage of the data set we expect to have values between 40 and 70 as well as for more than 70. Now determine the percentage of data points in the dataset that fall within this range, using same strategy as above for counting data points in the data set. How do each of these compare with your prediction and why is there a difference? Predicted percentage between 40 and 70 ______________________________ Actual percentage _____________________________________________ Predicted percentage more than 70 miles ________________________________ Actual percentage ___________________________________________ Comparison ____________________________________________________ _______________________________________________________________ Why? __________________________________________________________ ________________________________________________________________

1. The null and alternative hypotheses are given. Determine whether the parameter that is being tested.

Parameter: (Population mean, Population proportion, Sample mean, Sample proportion)

a. H₀: μ = 9.5
H₁: μ ≠ 9.5   

b. H₀: p =0.05
H₁: p < 0.05

1.B) A referendum for an upcoming election is favored by more than half of the voters.

1. Is this about a mean or a proportion?

a. proportion

b. mean

2. Identify the null hypothesis, the alternative hypothesis for a hypothesis test of this statement.

H_o: p

a. = 0.50

b. < 0.50

c. > 0.50

H_1: p

a. > 0.50

b. = 0.50

c. < 0.50

Save your answers for the next question.

1.C) The dean of a major university claims that the mean number of hours students study at her University (per day) is 3.2 hours. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis?

*In the last question I gave you the null and alternative hypotheses, write the correct hypotheses in this question and then answer appropriately.

a. There is not sufficient evidence to reject the claim μ = 3.2.

b. There is not sufficient evidence to support the claim μ ≤ 3.2.

c. There is sufficient evidence to reject the claim μ = 3.2.

d. There is sufficient evidence to support the claim μ = 3.2.

1.D) A 4-year college claims that the percentage of their students that graduate on time is 91.3%.

A student decides to test this claim with the following hypothesis test.

H_o: p = 0.913

H₁: p ≠0.913

With respect to the situation described in this problem, what is a type 1 error?

a. The evidence suggests that the percentage of students that graduate on time is 91.3%, but in fact the percentage is equal to 91.3%

b. The evidence suggests that the percentage of students that graduate on time is equal to 91.3%, but in fact it is different than 91.3%.

c. The evidence suggests that the percentage of students that graduate on time is different than 91.3%, but in fact it is less than 91.3%.

d. The evidence suggests that the percentage of students that graduate on time is equal to 91.3%, but in fact it is greater than 91.3%
