A study was conducted to determine the effectiveness of a certain treatment. A group of 112 patients were randomly divided into an experimental group and a control group. The table shows the result for their net improvement. Let the experimental group be group 1 and the control group be group 2. E Click the icon to view the net improvement results. (a) Test whether the experimental group experienced a larger mean improvement than the control group at the a=0.01 level of significance. State the null and alternative hypotheses. Choose the correct answer below. A. Ho: H1 = H2 and H1: H1>H2 O B. Ho H1= H2 and H1: 1 < P2 O C. Ho: H1 =H2 and H1: H1 # H2 Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.)
