If can't complete it all, I can post more questions just let me know!!
Solution:
Question 1
Part a
Answer: True
For the given regression model, the response variable is given as 1993 winnings and explanatory variable is given as the average number of putts per hole.
Part b
Answer: True
We are given R^2 = 0.081
So, correlation coefficient = r = sqrt(0.081) = 0.284605
r = 0.285
Part c
Answer: True
We are given the slope as -4139.2 which indicate a decrement of -4139.2 in response variable as per increase of one unit in explanatory variable.
Part d
Answer: True
The regression equation is given as below:
1993 winnings = 7897.2 – 4139.2*Average putts
We are given average putts = 1.75
1993 winnings = 7897.2 – 4139.2*1.75
1993 winnings = 653.6 thousand dollars
1993 winnings = $653,600.00
Question 2
We are given n = 69
df = n – 1 = 69 – 1 = 68
Question 3
The value of the intercept of the least squares regression line is given as 7897.2.
Question 4
The value of the slope of the least squares regression line is given as - 4139.2.

for these questions I need help on just the questions on all of them where it says "what is the value of the sample test statistic?" 24.) The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 36 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9thousand miles. Does this indicate that the average miles driven per...
Please explain steps and solve
thanks
