Question

Suppose you are testing The sample is large (n = 71) and the variance, σ2, is known. H0:μ=20 vs H1:μ>20. (a) Find the critical value(s) corresponding to α = 0.08. (b) You find that z = 1.56. Based on your critical value, what decision do you make regarding the null hypothesis (i.e. do you Reject H0 or Do Not Reject H0)?

Answer:We reject the null hypothesis.

Step-by-step explanation:We are

given the followingin the question:Sample size, n = 71

Alpha, α = 0.08

Population variance is known.

First, we design the null and the alternate hypothesis

We use One-tailed z test to perform this hypothesis.

Formula:a) We calculate the

z-criticalwith the help of z-table.b)

Since,

We fail to accept the null hypothesis and reject the null hypothesisand accept the alternate hypothesis.
