Expert Solution

The hypothesis being tested is:

H0: There is no correlation between smoking and an elevated resting pulse rate

Ha: There is a correlation between smoking and an elevated resting pulse rate

The p-value is 0.4909.

Since the p-value (0.4909) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Therefore, we cannot conclude that there is a correlation between smoking and an elevated resting pulse rate.

Using the data from 15 automobile accidents, the correlation coefficient between the combined speeds of the cars (x) in an accident and the amount of damage done (y) is 0.7831. The regression equation for the two variables is y = 801.518 + 162.845x. a. Is this a significant correlation? b. If the answer to last part is YES, then predict the amount of damage done in an accident in which the combined speeds of the car involved was 100 mph.
