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 µg/mL. Assume
the underlying population distribution of concentrations is
normally distributed.
ModA
*6.30 Find a 95% CI for the population mean concentration.
*6.31 Find a 99% Cl for the population variance of the
concentrations.
*6.32 How large a sample would be needed to ensure
that the length of the CI in Problem 6.30 is 0.5 ug/mL
assuming the sample standard deviation remains at
2.0 µg/mL?
