HYPOTHESIS TESTING FOR POPULATION MEAN P-value Method

Step 2: Calculate the value of the test statistic under the null hypothesis being true. If ˙2 known, use z 0 = x 0 ˙= p n. If ˙2 unknown, and parent population is normal, use t 0 = x 0 s= p n; Step 3: Compute the p-value associated with the test statistic. (i) Determine the reference distribution (a Zor t n 1). (ii) Find the p-value: ................
