Consider the following competing hypotheses: (You may find it useful to reference the appropriate table: z table or t table) Hypotheses: H0: ?D ? 2; HA: ?D > 2 Sample results: d? = 5.6, sD = 6.2, n = 10 The 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. (Round all intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)
