# Question

For a random selection of U.S. cities, the following data show the number of days for which the precipitation is greater than or equal to 0.01 inch and the number of days for which there is at least 1 inch of snow and/or sleet. Is there a significant linear relationship between the variables?

Perform the following steps.

a. Draw the scatter plot for the variables.

b. Compute the value of the correlation coefficient.

c. State the hypotheses.

d. Test the significance of the correlation coefficient at α = 0.05, using Table I.
