How do you find p-value from z-statistic? To calculate the p-value, first find the test statistic, a value that results from the particular "test" you are using to analyze the data. Then determine the p-value associated with the test statistic either by using technology or a table.What...
(a) Calculate the test statistic z used in testing Ho: p = 0.70, Ha: p > 0.70; with the sample n = 315 and x = 255. What is a sampling error? Could the value of the sampling error be zero and what would this mean? Find the sample standard deviation for the following data ...
