The length, \( X \) centimeters of eels in a river may be assumed to be normally distributed with mean 48 and standard deviation 8 . a) Exactly \( 60 \mathrm{~cm} \); b) Less than \( 60 \mathrm{~cm} \); c) Within \( 5 \% \) of the mean length. Normal distribution and confidence intervals

Walleye is a common game fish. Adult walleye have a length with a mean of 44 cm and a standard deviation of 4 cm and the distribution of lengths is Normal. What proportion of walleye are between 40 and 48 cm in length? Select one: a. 0.68 b. 0.95 c. 0.997 d. 0.50 e. Cannot be determined

9. Suppose that the lengths of the trout fry in a pond at the fish hatchery have the overall standard deviation of 0.8 inch. A random sample of 49 fry will be netted and their lengths measured. a) What is the probability that the sample mean will be within 0.2 inch of the population mean? b) Suppose the sample mean of the 49 fry netted is xbar = 3.4 inches. Construct a 95% confidence interval for the overall mean lengths of the trout fry in the pond.
