Question

Find the p-value in a test of the claim that the mean IQ score of acupuncturists is equal to 100, given that the test statistic is z=-2.00.

Answer 1

Answer #1

solution:

this is the two tailed test .

The null and alternative hypothesis is ,

H0 : = 100

Ha : 100

Test statistic = z=-2

P(z < -2) = 0.0228

P-value = 2*0.0228=0.0456
