The test statistic of z=-3.32 is obtained when testing the claim that p=1/2. a. Using a significance level of a=0.05​, find the critical​ value(s). b. Should we reject H0 or should we fail to reject H0 ​?

The critical value and the conclusion are mathematically given as

z_{0.05}=1.960 and  z<Zcritical, therefore we Reject H_o

What are the critical value and the conclusion?

a)Test statistic  z=-3.32

Claim: p< 0.5

a=0.05

critical value z_{0.05}

z_{0.05}=1.960

b)

z<Zcritical,

Beause z=-3.32< z_{0.05}=1.960 Reject H_o

In conclusion,

z_{0.05}=1.960 and  z<Zcritical, therefore we Reject H_o
