Consider the following competing hypotheses: (You may find it useful to reference the appropriate table: z table or ttable)Hypotheses: He: HD 3 3; HA: HD > 3Sample results: d = 5.7, sD = 6.9, n = 22The following results are obtained using matched samples from two normally distributed populations:a. Calculate the value of the test statistic, assuming that the sample difference is normally distributed. (Negative value should beindicated by a minus sign. Round final answer to 3 decimal places.)Test statisticb.
