You may need to use the appropriate technology to answer this question. Consider the following hypothesis test: H0: Ī¼d ā¤ 0 Ha: Ī¼d > 0 (a) The following data are from matched samples taken from two populations. Compute the difference value for each element. (Use Population 1 - Population 2.) (b) Compute dĢ. (c) Compute the standard deviation sd. (d) Conduct a hypothesis test using Ī± = 0.05. Calculate the test statistic. (Round your answer to three decimal places.) Calculate the p-value. (Round your answer to four decimal places.) p-value = What is your conclusion? Reject H0. There is sufficient evidence to conclude that Ī¼d > 0. Reject H0. There is insufficient evidence to conclude that Ī¼d > 0. Do not reject H0. There is insufficient evidence to conclude that Ī¼d > 0. Do not Reject H0. There is sufficient evidence to conclude that Ī¼d > 0.

There is sufficient evidence to conclude that Ī¼d > 0.
Consider the following hypothesis test. H0: Ī¼1 - Ī¼2 ā¤ 0 Ha: Ī¼1 - Ī¼2 > 0 The following results are for two independent samples taken from the two populations. Sample 1: n1 = 45, xĢ1 = 25.7, Ļ1 = 4.9 Sample 2: n2 = 50, xĢ2 = 22.7, Ļ2 = 7.0 a. What is the value of the test statistic (round to 2 decimals)? b. What is the p-value (round to 4 decimals)? Use z-value rounded to 2 decimal places. c. With Ī± = 0.05, what is your hypothesis testing conclusion? p-value is [Select your answer] H0 greater than 0.05, do not reject less than or equal to 0.05, reject
