Suppose the following data were collected from a sample of 5 car manufacturers relating monthly car sales to the number of dealerships and the quarter of the year. Use statistical software to find the following regression equation:

SALESi=b0+b1DEALERSHIPSi+b2QUARTER1i+b3QUARTER2i+b4QUARTER3i+ei

Is there enough evidence to support the claim that on average, car sales are higher in the 4^th quarter than in the 3^rd quarter at the 0.05 level of significance? If yes, write the regression equation in the spaces provided, rounded to two decimal places. Else, select "There is not enough evidence."

Selecting a checkbox will replace the entered answer value(s) with the checkbox value. If the checkbox is not selected, the entered answer is used.

what am I doing wrong here? thank you!

Chapel Hill has decided to see if there is less drunk driving during the quarantine along a checkpoint on 15-501. It is known that before the quarantine the number of impaired drivers in an evening on 15-501 is normally distributed with mean of 73.5.

A) If the police department checks the data after quarantine for 7 evenings and gets the following results: 71, 66, 63, 72, 74, 70, 67.
What is the variance of this sample? _____
What is the value of our test statistic? _____
What is our p-value for the test? _____

B) Let's say we still don't know if drunk driving behavior has changed, but the Chapel Hill police department has been accused of "juking the stats" (inflating arrest numbers for nefarious reasons) so they've bought a new brand of breathalyzers so they can test every individual twice to make sure their drunk driving convictions stick. The police department wants to check if the blood alcohol content measurements for the new tests are different from the old tests. The first 12 measurements from breathalyzer 1 (multiplied by 10,000) are as follows:
4.4
2.1
3.6

Susan wants to buy a house for $200,000. US Bank will give her the loan at 3.5% for 30 years if she puts 20% down and Dacotah Bank will give her the loan at 3.8% for 30 years if she puts 10% down. There are NO other options. (15 PTS) a. Which loan should she sign up for? Pick one, no explanation needed. What is her monthly payment? (5 PTS) b. After 5 years, Susan is approached by a philanthropic group known as C.S.C. They offer to lend her $50,000 interest free for an indefinite period of time, provided she joins their group. Susan takes up the offer and uses the money to pay off some of her mortgage. What will be her new NPER (how many years will it take for her to pay off her remaining mortgage)? (5 PTS) c. After another 7 years, a private bank offers to take over the remaining mortgage at 3%. What will be her first month interest payment if she signs up with them? (To do this, find the remaining mortgage after 12 years. Use this mortgage amount as the new principle. First month interest payment will be the monthly rate multiplied by principle). (5 PTS) d. (Bonus Question): Assume, there is a $1,000 one-time processing fee for signing up with the private bank in the previous part (c). Does it make sense to move the mortgage over to the private bank @ 3%? Explain. (5 PTS).
