The accompanying data file shows matched pairs observations for a before and after experiment. Assume that the sample differences are normally distributed. (You may find it useful to reference the appropriate table: table or table) Deicture Click here for the Excel Data File Hint. The differences are calculated as Xbefore - Xafter. a. Construct the competing hypotheses to determine if the experiment increases the value of the observations, HO: Hp = 0; HAH MD * 0 1 p = 0; 0 b. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test statistic c. Find the p-value? O p-value
