What is the Critical Value for the test statistic?
Ho : μ = 7
Ha : μ ≠ 7
Variance Known
α = 0.01
n = 20
Homework Answers
We know that this is a two tailed test.
Also, we know the population variance. Thus, we may use a z-distribution.
Thus, at Z0.01/2 = Z0.005, we know that the value from the standard normal table is= 2.575.
Thus, the critical values are -2.575 and +2.575.
