Question

The data below shows the high temperatures and the times (in minutes) runners who won a marathon. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using =0.05. Is there sufficient evidence to conclude that there is a linear correlation between temperature and winning times? Temperature (x)6060 4563 Time 70 73 58 | 146.299 148.415 144.659 147. 335 What are the null and alternative hypotheses? A. Ho:=0 O B. Ho : =0 H1: p>0 Construct the scatterplot. Choose the comect graph below OA. o. o
