d p 0 89 Recall the previously determined values po 0 85 and n 160 Now we are to find the test statistic for a new sample proportion p 0 89 Use these values to find the test statistic rounding the result to two decimal places Z p Po Po 1 PO n 0 89 0 85 1 42 0 85 1 0 85 160 1 42 0 85 Step 13 A lower tail test is being performed so the area to the left of the test statistic z 1 42 is needed Use the standard normal table to find the p value for this test statistic rounding the result to four decimal places p value
