PLEASE HELP ME SOLVE THIS WITH ALL STEPS!! I WOULD REALLY APPRECIATE IT!

What is the forecast for the number of books sold if the number of sales calls made is 3,000 ? Round to the nearest whole number. 1,358 1,670 1,284 Question 3 4 pts What percent of the variation in the number of books sold is explained by the number of sales calls made? Answer as a \% with one decimal place. 26.0% 21.5% What is the value of the correlation coefficient? Round to four decimal places. 0.2596 0.5095 0.5095 Question 5 4 pts He wants to test to determine whether a stationary model is appropriate for forecasting the value of Y by using a two-step hypothesis testing procedure and a significance level of 0.05 . [T/F] The null and alternative hypotheses that he must develop are HO:1 =O (No linear trend is present). HA:1=O ( A linear trend is present). True False Use the following problem statement to answer questions 2-6. Chris, as a book publisher, believes that the number of books sold ( Y ) is influenced by the number of sales calls made (X) by his sales force. The following is a partial computer output of regression analysis. What is the forecast for the number of books sold if the number of sales calls made is 3,000 ? Round to the nearest whole number. He wants to test to determine whether a stationary model is appropriate for forecasting the value of Y by using a two-step hypothesis testing procedure and a significance level of 0.05 . [T/F] The conclusion that he should make is that he rejects HO. It means that there is a linear trend between two variables. True False
