A Null Hypothesis H₀: μ ≥ 2

question 19

Short Answer

A null hypothesis H₀: μ ≥ 2.4 is not rejected at a significance level of .04 (α = .04). The standard deviation for the normally distributed population is known to be .40. Determine the probability of a Type II error, if we assume that the actual mean is 2.125 based on a sample size of 16.
