Happy Lodge Ski Resorts tries to forecast monthly attendance. The management has noticed a direct relationship between the
average monthly temperature and attendance.
Average
Month Temperature
Resort Attendance
(in thousands)
1
22
43
2
27
34
32
39
35
32
42
27
a. Given five months of average monthly temperatures and corresponding monthly attendance, compute a linear regression
equation of the relationship between the two. (Round your answer to 2 decimal places, the tolerance is +/-0.01. For negative
amounts use a negative sign preceding the number e.g. -45.)
Resort attendance =
(average temperature)
If next month's average temperature is forecast to be 45 degrees, use your linear regression equation to develop a forecast. (To
achieve this answer do not round your interim calculations. Round your answer to 1 decinal place, e.g. 25.2.)
Resort attendance =
thousand attendees.
b. Compute a correlation coefficient for the data and determine the strength of the linear relationship between average
temperature and attendance. How good a predictor is temperature for attendance? (Round your answer to 2 decimal places,e.g.
25.22.)
