A test has power 090 when mu 15 The probability of rejectin

A test has power 0.90 when mu = 15. The probability of rejecting H_o when mu = 15 is 0.90. The probability of making a correct decision when mu = 15 is 0.90. The probability that H o is true when mu = 15 is 0.10. The probability of making a correct decision when mu = 15 is 0.10.

Solution

C)

The probability that H0 is true when mean=15 is 0.10

(Power= P(Type II error) =P(Accept ho when Ho when Ho is false)
