1. Maximum power grip strength was measured on 8 female stroke survivors in neutral posture. The following data were computed: n=8,X-bar:32lbss.:9lbs A. Determine the 95% confidence interval for the sample distribution (i.e., individual measurements). B. Determine the 95% confidence interval for the sample mean. C. Age-matched healthy female grip strength is 68lbs. Test the null hypothesis that the measured mean grip strength of the stroke survivors is half that of healthy controls (i.e., test whether the mean of 32lbs is statistically different than the expected value of 34lbs ). Assume =0.05
