1) The weights of the fish in a certain lake are normally distributed with a mean of 20 lb and a 1). standard deviation of 9. If 9 fish are randomly selected, draw, label and shade the normal curve, find the z-scores, and find the probability that the mean weight will be between 17.6 and 23.6 lb. Draw, label, and shade: Z-scores: P(17.6<x< 23.6)

The weights of packages shipped via a national delivery company follows a normal distribution with mean 24.6 pounds and standard deviation 4 pounds. a.) What is the probability that a randomly selected package will weigh more than 25 pounds? b.) A local delivery truck has a capacity of 7,250 pounds. If 290 packages are loaded onto the truck, what is the probability that the weight capacity will be exceeded?

A candy maker produces mints whose weight follows a normal
distribution with mean
21:37g and standard deviation 0:4g. Suppose 15 mints are selected
at random. Let Y be
the number of mints among them that weigh less than 20:857g. Then,
P(Y 2) = 0:816.

Probability question
The owner of a fish market determined that the mean weight for a catfish is 3.2 pounds assuming that the weight of a catfish follows a normal distribution and its standard deviation is unknown. He also knew that that probability of a randomly selected catfish that would weigh more than 3.8 pounds is 20% and the probability that a randomly selected catfish that would weigh less than 2.8 pounds is 30%. What is the probability that a randomly selected catfish...
