Susan recently switched her primary doctor to one specializing in caring for elderly patients. On her new doctor's website, it says that the mean systolic blood pressure among elderly females is 15 millimeters of mercury (mmig). Susan believes the value is actually higher. She bases her belief on a recently reported study of 14 randomly selected, elderly females. The sample mean systolic blood pressure was 128 mmlig, and the sample standard deviation was 23 mmlig. Assume that the systolic blood pressures of elderly females are approximately normally distributed. Based on the study, at the 0.10 level of significance, can it be concluded that i, the population mean systolic blood pressure among elderly females, is greater than 115 mmlg? Perform a one-tailed test. Then complete the parts below. Curry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (@) State the null hypothesis /, and the alternative hypothesis H. P H :1 X S p H, :0 (b) Determine the type of test statistic to use. (Choose one) 0=0 030 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) D=0 00 0 X 5 ? (d) Find the p-value. (Round to three or more decimal places.) (e) Can it be concluded that the mean systolic blood pressure among elderly females is greater than 115 mmlg? OYes ONo
