Question 915811: Assume the significance level is a=0.05. Use the given information to find the P- value and the critical value(s). The test statistic of z=1.50 is obtained when testing the claim that p>0.2.
P value =
critical value = Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! Ho: p ≤ 0.2
Ha: p > 0.2 (claim)
test stat: z = 1.50
.05 significance level, one-tailed
critical value = z = invNorm(.95) = 1.645
P(z > 1.645)...(area under the standard normal curve to the right of blue line represents the critical area)
1.50 < 1.645, accept Ho, (test results do not support claim)
