An ecologist randomly samples 16 plants of a specific species and measures their heights. He finds that this sample has a mean of 13 cm and a standard desabon of 1 cm. If we assure that the height measurements are normally distributed, find a 95% confidence interval for the mean height of all plants of this species. Then complete the table below Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If...

An ecologist randomly samples 20 plants of a specific species and measures their heights. He finds that this sample has a mean of 13 cm and a standard deviation of 3 cm. If we assume that the height measurements are normally distributed, find a 95% confidence interval for the height of all plants of this species. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place (if necessary,...

A researcher wants to estimate the proportion of depressed individuals taking a new anti-depressant drug who find relief. A random sample of 225 individuals who had been taking the drug is questioned; 173 of them found relief from depression. Based upon this, compute a 99% confidence interval for the proportion of all depressed individuals taking the drug who find relief. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to two...
