I have done some work, cannot complete. Plz help.

Consider the following hypothesis test. Ho: HSO Ha : H > O (a) The following data are from matched samples taken from two populations. Compute the difference value for each element. (Use Population 1 - Population 2.) Population Element 2 Difference 1 21 21 0 2 28 27 1 3 18 0 4 20 18 2 5 26 24 2 (b) Compute d. (c) Compute the standard deviation S - 1.67332 X (d) Conduct a hypothesis test using a = 0.05. Calculate the test statistic. (Round your answer to three decimal places.) 054 X Calculate the p-value. (Round your answer to four decimal places.) p-value = .3105 X
