A test is made of H0 : µ = 17 versus H1 : µ < 17 is performed using α = 0.01 significance level. The value of the test statistic is z = -2.68 and it is concluded that H0 is rejected.
If the true value of µ is 17, is the conclusion a Type I Error, Type II error, or a correct decision?
Type I
Type II
Correct Decision
A test is made of H0 : µ = 17 versus H1 : µ < 17 is performed using α = 0.01 significance level. The value of the test statistic is z = -2.68 and it is concluded that H0 is rejected.
If the true value of µ is 10, is the conclusion a Type I Error, Type II error, or a correct decision?
Type I
Type II
Correct Decision
A test is made of H0 : µ = 50 versus H1 : µ =/= 50 is performed using α = 0.01 significance level. The value of the test statistic is z = -2.68 and it is concluded that we fail to reject H0 .
If the true value of µ is 65, is the conclusion a Type I Error, Type II error, or a correct decision?
Type I
Type II
Correct Decision
