Pharmacology Suppose we want to estimate the concentration (ug/mL) of a specific dose of ampicillin in the urine after various pe- riods of time. We recruit 25 volunteers who have received ampicillin and find they have a mean concentration of 7.0 ug/mL with a standard deviation of 2.0 ug/mL. Assume the underlying population distribution of concentrations is normally distributed. *6.30 Find a 95% Cl for the population mean concentration. *6.31 Find a 99% CI for the population variance of the concentrations. bn 8.8 *6.32 How large a sample would be needed to ensure that the length of the Cl in Problem 6.30 is 0.5 ug/mL assuming the sample standard deviation remains at 2.0 μg/mL?

Solve the following by setting up the proper equations to describe the facts given and then carrying out the mathematical calculations to solve for the unknown variable(s). Let x represent length and y represent width. Enter your answer in (x, y) format. The length of a rectangle is 3 times the width. The difference between the length and width is 14 feet. Determine the rectangle's length and width.
