Supposed to be buddy for the test was found to be .0268. state correct inclusion 00.020 QUESTION 3 Solve the problem. Consider the following printout. HYPOTHESIS: MEAN X x x gpa SAMPLE MEAN OF X = 3 ,0512 SAMPLE VARIANCE OF X = 0230731 SAMPLE SIZE OF X = 167 HYPOTHESIZED VALUE (x)3 MEAN X-x = 0.0512 z= 1.3774 Suppose a two-tailed test is desired. Find the p-value for the test. p = 0.1676 p = 0.8324 p = 0.9162 QUESTION 4

Explanation / Answer

Solution:- p = 0.1676

z = 1.3774

For two tailed test we need to find the p-value to the extreme of 1.3774.

P( - 1.3774 > z > 1.3774) = P(z > 1.3774) + P(z < - 1.3774)

P( - 1.3774 > z > 1.3774) = 0.0838 + 0.0838

P( - 1.3774 > z > 1.3774) = 0.1676
