(b) Calculate by hand the test statistic.
(c) Use the appropriate sheet in the Hypothesis Test andConfidence Interval template to complete all relevant computations(including the test statistic: compare with (b) to confirm yourcalculation is correct). Add a screenshot.
(d) Use the P-value obtained in (c) to explain whether or notthe null hypothesis is rejected.
(e) Make a concluding statement.
(f) Comment on potential issues related to the validation ofyour result (Hint: the sub-
