Question 1177046: 3.)An ecologist randomly samples 14plants of a specific species and measures their heights. He finds that this sample has a mean of
17 cm and a standard deviation of 1 cm. If we assume that the height measurements are normally distributed, find a
99% confidence interval for the mean height of all plants of this species. Then find the lower limit and upper limit of the
99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
Lower limit
Upper Limit

Hi
sample = 14, mean=  17cm  and s = 1cm
99% confidence interval - two tailed 

t(df13) = 3.106*1/sqrt(17) = .83
CI: (16.2 , 17.8)

Wish You the Best in your Studies.
