Four hospitals tracked their patient wait times over a single shift Their means compared using ANOVA. The test used a = 0.05.Is the cfficientl of hospiul significant at a = .05? Choose the best . answer.Yes. F is greater than F-crit nNo since F is less than F-crit C No since P-value is less than F-cnt D. Yes since P-value is greater than 0.05 A hypothesis test may show that the difference between two means is statistically significant (especially if the sample size is very large), yet the difference may have little practical importance.

Solution

1. Is the effect of hospital significant?

OPTION B: No, since F < Fcrit. (1.79 < 3.1599)

********************

2.

A. TRUE.

This is true when, for example you know that the difference between the lengths of two species of fishes cannot be by chance (too consistently that way!), but may be too small (ex., just 2 mm difference).
