I need the right answer to this problem.
Transcribed Image Text:A regression was run to determine if there is a relationship between hours of TV watched per day (x) and
number of situps a person can do (y).
The results of the regression were:
y=ax+b
a=-0.836
b=36.418
r²-0.758641
r=-0.871
Use this to predict the number of situps a person who watches 1 hours of TV can do (to one decimal place)

- Can you please solve this problem and all of the sub problem A through D and show all of the steps to the solution please and thank youarrow_forwardWhile working on the multiplication problem 38 x 25, Maria says this: “Four times 25 is 100, so 40 times 25 is 1000. Now take away 2, so the answer is 998.” Is Maria’s method correct or not? If it is correct, write equations that incorporate Maria’s work and that show why it’s correct. If Maria’s reasoning is not correct, explain why. Work with portions that are right to correct Maria’s work, and write a string of equations that corresponds to your corrected method for calculating 38 x 25. In either case, write your equations in the following form:arrow_forwardA tutoring service provides tutoring for a fee. When the tutoring service charges $11/hour, there is a demand for 28 tutors per week. When the hourly rate rises to $17/hour, the demand drops to 16 tutors per week.

Find the price per hour at which the number of tutors demanded and the number of tutors supplied will be equal.arrow_forward
- So I decide to go to Cinnaholic once day and I buy two cinnamon rolls. I notice that these cinnamon rolls do not appear to be the same size, so naturally I eat the smaller one first and then eat the bigger one. As I am sitting on my couch stuffed from those delicious rolls, I start to think, "I wonder if Cinnaholic makes their cinnamon rolls to the size they claim them to be." Of course I have to go and purchase several rolls, weigh them (in ounces), and eat them. 30 pounds later, I have collected all of my data and tabulated it below: Cinnamon Roll Weight 5.6, 6.3, 6.1, 6.1, 5.9, 5.8, 6.0, 6.0, 6.1, 6.3, 6.3, 6.3, 6.4, 5.8, 5.7. Cinnaholic claims that their Cinnabon rolls are made to weigh 6.1 ounces on average. The mean is 6.0467 Standard deviation: 0.2475arrow_forwardHello, Can you explain problem c) I do not understand the solution.arrow_forwardCan you please help me solve without the use of technology?arrow_forward
