Data was collected to explain an employee’s annual income raise (expressed in $’s) based on the employee’s rating (on a scale of 1-20) Based on the regression results, answer the following questions g) What is the effect on “raise” of getting a 1 point higher rating? h) What is the 95% confidence interval for the coefficient of rating?

To determine if the number of hours of exercise per week is significantly correlated with quality of sleep, you measure these values on 20 participants.  What is the critical value you need in order to determine if your correlation coefficient is significant at p=0.05. Use 3 decimal places

Hi,  I am having trouble finding the P-value for this problem. Could you please explain step by step how will I figure out the P-value? Thanks.

Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded during a flight. Find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet). Altitude Temperature a. Find the explained variation. (Round to two decimal places as needed.) 2 55 8 40 13 25 20 - 3 28 - 26 31 - 41 34 - 53
