5. A certain study involved patients whose melanoma did not respond to existingtreatments. The presence of cells that trigger an immune response in the body ismonitored since they may help fight cancer. Here are data for the 11 subjects: counts ofactive cells per 100,000 cells before and after infusion of the modified cells.Before142016After417121520700135303592108Construct a 95% confidence interval for the difference in the mean counts of active cells per100,000 cells.

The CEO of a large financial institution claims that, on average, their clients invest more than R150 000 per year in a particular portfolio. Test this claim at the 10% significance level if it was found that a sample of 25 clients invested an average of R145 000 in the portfolio over the last year, with a standard deviation of R15 000.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 143 136 121 129 135 Left arm 167 171 189 139 142 In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? A. H0: μd≠0 H1: μd>0 B. H0: μd=0 H1: μd<0 C. H0: μd=0 H1: μd≠0 Your answer is correct. D.

Right arm Left arm 150 142 120 131 167 160 179 156 In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: Hd = 0 H₁: Hd 0 Since the P-value is than the significance level, the null hypothesis. There sufficient evidence to support the claim of a difference in measurements between the two arms.
