Dаtа оn hоurs оf sunlight аnd beach attendance were collected for 30 randomly selected summer days at Miami Beach. A linear regression analysis was then conducted to examine the relationship between these variables, using hours of sunlight to predict the number of beach visitors. The results of the analysis are presented below. 3 points a) From the JMP output, provide the equation of the linear regression line. 2 points b) Using your previous linear regression line, predict the number of beach visitors for a summer day with 10.4 hours of sunlight. 2 points c) From the data set, it was observed that there were 7,900 beach visitors for 10.4 hours of sunlight. What is the prediction error (ie. residual) for this data point? 3 points d) How would you describe the strength of the linear relationship? Justify your description by providing the correlation value.
