Let *1, x2, ..., Xnbe random samples from N (µ, 1) population. Consider the following hypotheses Ho : μ=-2 υ. s. Η : μ--3 and the rejection region {T : a < -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-Ill error Bis smaller than 0.01. (Hint: you need to round UP to the nearest integer.) Let *1, x2, ..., Xnbe random samples from N (µ, 1) population. Consider the following hypotheses Ho : μ=-2 υ. s.
