Question

For the hypothesis test H₀: μ = 10 against H₁: μ > 10 and variance known, calculate the P-value for each of the following test statistics.

(a) z₀ = 2.15,

(b) z₀ = -1.75

Answer 1

Answer #1

We have given,

Right tailed test.

(a) P value =0.0158............by using Z table or Excel =1-NORMSDIST(2.15)

(b) P value =0.9599..............by using =1-NORMSDIST(-1.75)
