If b results in t-test what is the degrees of freedom?
Lashonda 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 120 millimeters of mercury (mmHg). Lashonda believes the value is actually higher. She bases her bellef on a recently reported study of 17 randomly selected, elderly females. The sample mean systolle blood pressure was 131 mmHg, and the sample standard deviation was 20 mmHg Assume that the systolic blood pressures of elderly females are approximately normally distributed. Based on the study, at the 0.05 level of significance, can be concluded that, the population mean systolic blood pressure among elderly females, is greater than 120 mmHg7 Perform a one-talled test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis Hy @ P H 0 EX 5 co 6 ma 음 (6) Determine the type of test statistic to use (Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places D. OS m2 Dw x (a) Find the p-value (Round to three or more decimal place) (0) Can it be concluded that the mean systolic blood pressure among elderly females is greater than 120 mmig? Yes No
