Question:
You obtain a sample of N = 15 frogs, where the average weight in grams (X ) equals 23.2 grams and s = 1.1. You wish to conduct a hypothesis test specifyingH0:0= 24 grams.
(f) Report the T-Score test statistic (T). Round your answer tothreedecimal places.
(g) Based on the T-Score test statistic (T) in (f), do you have sufficient evidence to rejectH0when= 0.05?
(h) Based on the T-Score test statistic (T) in (f), do you make a Type I or Type II error when= 0.05?
(i) Based on the T-Score test statistic (T) in (f), do you have sufficient evidence to rejectH0when= 0.01?
(j) Based on the T-Score test statistic (T) in (f), do you make a Type I or Type II error when= 0.01?
(k) SupposeH0is false (H0:0= 24 grams). Would you expect to rejectH0more easily when N = 35 or when N = 15?
(l) SupposeH0is false (H0:0= 24 grams). Would you expect to rejectH0more easily when= 0.05 or when= 0.01?
(m) SupposeH0is false (H0:0= 24 grams). Would you expect to rejectH0more easily when= 25 grams or when= 26 grams?
