Need the Z for Part A and Z and P Value for Part B Thank you! Label them as well! I will give a good rating
Pilates is a popular set of exercises for the treatment of individuals with lower back pain. The method has six basic principles: centering, concentration, control, precision, flow, and breathing. An article reported on an experiment involving 88 subjects with nonspecific low back pain. The participants were randomly divided into two groups of equal size. The first group received just educational materials, whereas the second group participated in 6 weeks of Pilates exercises. The sample mean level of pain (on a scale from 0 to 10) for the control group at a 6-week follow-up was 5.1 and the sample mean for the treatment group was 3.2; both sample standard deviations were 2.3. (a) Does it appear that true average pain level for the control condition exceeds that for the treatment condition? Carry out a test of hypotheses using a significance level of 0.01. State the relevant hypotheses. Ho: "control - "treatment = 0 Ha control "treatment 0 Ho: "control - "treatment = 0 Ha: "control - "treatment 2 0 Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = 4.078 P-value = .0001 State the conclusion in the problem context. Reject Ho. The data suggests that true average pain level for the control condition exceeds that for the treatment condition. Fail to reject Ho. The data does not suggest that true average pain level for the control condition exceeds that for the treatment condition Reject Ho. The data does not suggest that true average pain level for the control condition exceeds that for the treatment condition. Fail to reject Ho. The data suggests that true average pain level for the control condition exceeds that for the treatment condition. (b) Does it appear that true average pain level for the control condition exceeds that for the treatment condition by more than 1 at a significance level of 0.01? Carry out a test of appropriate hypotheses. State the relevant hypotheses. Ho: "control - "treatment = 1 Ha! "control - "treatment 1 Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = 2.0393 X P-value = 0.02071 State the conclusion in the problem context. Reject Ho. The data suggests that true average pain level for the control condition exceeds that for the treatment condition by more than 1. Reject Ho. The data does not suggest that true average pain level for the control condition exceeds that for the treatment condition by more than 1. Fail to reject Ho. The data suggests that true average pain level for the control condition exceeds that for the treatment condition by more than 1. o Fail to reject Ho. The data does not suggest that true average pain level for the control condition exceeds that for the treatment condition by more than 1
