The table surmmarizes the results of the two classes on their final exam. Complete parts (a) through (e) below. E Click the icon to view the table. Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.) Choose the correct conclusion. O A. Reject Ho. There is not sufficient evidence that the online homework is effective in raising final exam scores. O B. Do not reject Ho. There is sufficient evidence that the online homework is effective in raising final exam scores. OC. Do not reject Ho. There is not sufficient evidence that the online homework is effective in raising final exam scores. O D. Reiect Ho There is sufficient evidence that the online homework is effective in raising final exam scores
