3. ________ In a two-sided hypothesis test, the observed test statistic is determined to be Z = -2.5. The p-value for this test is

(A) 0.1091 (B) 0.0538 (C) 0.0062 (D) 0.0124

Can you explain your answer? thank you

Answer 1

Answer #1

solution:

this is the two tailed test .

Test statistic = z=-2.5

P(z <-2.5 ) = 0.0062 using z table

P-value = 2*0.0062=0.0124

p value =0.0124
