For the hypothesis test H0 7 against H1 7 and variance know

For the hypothesis test H0: = 7 against H1: 7 and variance known, calculate the Pvalue for each of the following test statistics.

(a) z0 = 2.05 (b) z0 =1.84 (c) z0 = 0.4

Solution

As we can see, this is a two tailed test. Thus, getting the two tailed P values of these z scores using table/technology,

a)

z0 = 2.05

P(z<-z0 or z > z0) = 0.040364431 [ANSWER]

**************

b)

z0 = -1.84

P(z<-z0 or z > z0) = 0.065768237 [ANSWER]

**************

c)

z0 = -1.84

P(z<-z0 or z > z0) = 0.689156517 [ANSWER]
