please I need help with this questions. I have arrived at the answers but I would like to double the steps to make sure I am doing the right thing. Thank you

1.) Which of the following are feasible equations of a least squares regression line for the annual population change of a small country since the year 2000?

Select all that apply.

(A) y=38,000+2500x

(B) y=38,0002500x

(C) y=38,000+2500x

(D) y=38,0002500x

(2.). Identify the parameter n in the following binomial distribution scenario. A basketball player has a 0.479 probability of making a free throw and a 0.521 probability of missing. If the player shoots 17 free throws, we want to know the probability that he makes more than 9 of them. (Consider made free throws as successes in the binomial distribution.)

(3.) Data is collected on the relationship between time spent playing video games and time spent with family. The data is shown in the table and the line of best fit for the data is y^=0.27x+57.5. Assume the line of best fit is significant and there is a strong linear relationship between the variables.

Video Games (Minutes)

30

60

90

120

Time with Family (Minutes)

50

40

35

25

According to the line of best fit, the predicted number of minutes spent with family for someone who spent 95 minutes playing video games is 31.85. Is it reasonable to use this line of best fit to make the above prediction? Select the correct answer below:

(A) The estimate, a predicted time of31.85 minutes,is unreliable but reasonable.

(B.) The estimate, a predicted time of31.85 minutes,is both unreliable and unreasonable.

(C.) The estimate, a predicted time of31.85 minutes,is both reliable and reasonable.

(D.) The estimate, a predicted time of31.85 minutes,is reliable but unreasonable.
