Let 21, x2, ..., Inbe random samples from N (u, 1) population. Consider the following hypotheses Ho : u = -2 v. s. H1 u = -3 and the rejection region {x : < -2.5}. 1. For n = 20, the type-l error a is and the type-Il error Bis (Please round to 2 significant figures.) 2. Calculate the smallest number of samples so that the type-II error Bis smaller than 0.01. (Hint: you need to round UP to the nearest integer.) Let 21, x2, ..., Inbe random samples from N (u, 1) population. Consider the following hypotheses Ho : u = -2 v. s.
