Kala 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). Kala believes the value is actually higher. She bases her belief on a recently reported study of 15 randomly selected, elderly females. The sample mean systolic blood pressure was 134mmHg, and the sample standard deviation was 21mmHg. 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 it be concluded that μ, the population mean systolic blood pressure among elderly females, is greater than 120mmHg? Perform a one-tailed test. Then complete the parts below. (a) State the null hypothesis H0 and the alternative hypothesis H1. (b) 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) 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 120 mmHg? Yes No

A layer of liquid B floats on liquid A. A ray of light begins in liquid A and undergoes total internal reflection at the interface between the liquids when the angle of incidence exceeds $34.9^\circ$. When liquid B is replaced with liquid C, total internal reflection occurs for angles of incidence greater than $48.5^\circ$. Find the ratio $n_B/n_C$ of the refractive indices of liquids B and C.
