The data set below includes observed high temperatures for 137 consecutive days in a city, along with predictions of this temperature made 1, 2, 3, 4, 5, 6, and 7 days before by a local weather station that advertises its ability to predict weather a week ahead. The data set also includes the 30-year average high temperature for each day. Complete parts (a) through (f). .:
(a) Summarize the simple regression of the high temperature on the 30-year average high temperature.
The simple regression equation is ý = + x
( (Round to three decimal places as needed.)
(b) Explain why the simple regression estimated in (a) does not meet the conditions required for the SRM. Select the correct choice and fill in the answer box to complete your choice. (Round to two decimal places as needed.) .
O A. The slope is not significantly different from zero. The test statistic is
O B. There is multicollinearity. The VIF is .
O C. There is a significant autocorrelation. The value of Pe is .
