Question

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test H0 : ? = 78 vs Ha : ? > 78 when the sample has n = 21 , x? = 82.2 , and s = 3.1 with SE = 0.7 . Find the value of the standardized z-test statistic. Round your answer to two decimal places. z =
