Somebody has calculated a correlation coefficient (r) of 0.83 for these variables. In the space 15) below, explain (using sentences for direction, and the appropriate calculation for strength) what this correlation coefficient means in terms of the relationship between the variables. ANSWER - 16) does/does Using a few sentences, provide your assessment of how the correlation coefficient in Q15 not match the relationship between these variables as shown on the scatterplot. ANSWER -

Freshcrim specializes in the sales of ice cream from street trolleys in the centers of many cities. Some factorsthat may determine the sales of ice cream are: the atmospheric temperature, the location of the trolley, therain and the humidity. However, there exists a hypothesis that the sales of ice cream during the summer aresignificantly correlated only with atmospheric temperature. They defined two variables: X : the meanatmospheric temperature and Y : the sales. They considered the month of July of this year in a randomsample of 30 cities. For each city in the sample, let x be the mean temperature in degrees Fahrenheit and ythe mean sales per day in dollars per 100,000 residents. The data are given below. A regression model wasrun, with Y as the dependent variable and X as the independent variable.
