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?
The number of days of precipitation and snowfall/sleet are shown.

Find y€™ when x = 100 days.
