Can you please help with the P and Z values with an explanation? All prior explanations leave out the P and Z to the right of the chart.

A competency test is modified so that the proportion of test-takers that pass is more than75%. A simple random sample of test-takers is collected to determine if the proportion of passers is greater than75%. The results of the sample are shown below.

Competency test sample passed 80 Observations 100 Confidence Level 0.9 Critical value 1.28 test statistic (z) 1.15 p-value 0.124 P = Ex: 1.234 -3 -2 -1 0 3 2 = Ex: 1.234 n. = Ex: 9 Number passed = Ex: 9 Sample proportion p = Ex: 1.234
