Consider the following hypothesis test. H0:20H3:<20 A sample of 50 provided a sample mean of 19.4 . The population standard deviation is 2 . (a) Find the value of the test statistic. (Round your answer to two decimal places.) (b) Find the p-value. (Round your answer to four decimal places.) p-value= (c) Using a=0.05, state your conclusion. Reject H0. There is sufficient evidence to conclude that <20. Reject H0. There is insufficient evidence to conclude that <20. Do not reject H0. There is sufficient evidence to conclude that <20. Do not reject H0. There is insufficient evidence to conclude that <20. (d) State the critical values for the rejection rule. (Round your answer to two decimal places. If the test is one-tailed, enter NonE for the unused tail.) test statistic test statistic.
