In an analysis of the accuracy of weather forecasts, the actual high temperatures
In an analysis of the accuracy of weather forecasts, the actual high
temperatures are compared to the high temperatures predicted one day earlier and the high temperatures predicted five days earlier. Listed below are the errors between the predicted temperatures and the actual high temperatures for consecutive days in a city. Do the standard deviations suggest that the temperatures predicted one day in advance are more accurate than those predicted five days in advance, as we might expect?
TABLE (ACTUAL HIGH) -( HIGH PREDICTED ONE DAY EARLIER): 1, 1, 1, 1, -4, -2, 2, -2, 8, 2, 0, -1, 0, 1
(ACTUAL HIGH)- (HIGH PREDICTED FIVE DAYS EARLIER): 0, -1, 2, 4, -7, -9, 4, -1, 7, -2, -2, -1, 7, -3
