y definition, jumbo shrimp are those that require between 10 and 15 shrimp to make a pound. Suppose that the number of jumbo shrimp in a 1- pound bag averages mu=12.5 with a standard deviation of sigma =1.5, and forms a normal distribution. What is the probability of randomly picking a sample of n= 25 1-pound bags that average more than M = 13 shrimp per bag?

The average weekly unemployment benefit in Idaho is $272. Suppose that the benefits are normally distributed with a standard deviation of $43. Find the probability that the average weekly u employment benefit of a random sample of 15 benefits chosen in Idaho is less than U.S. average, which is $299.

The weights of the guinea pigs in a laboratory are normally distributed with a mean weight of 2.1 pounds and a standard deviation of 0.8. What is the probability that a randomly selected guinea pig would weigh above 2.3 pounds?

An elevator has a placard stating that the maximum capacity is 4400 lb-29 passengers. So, 29 adult male passengers can have a mean weight of up to 4400/29 = 152 pounds. Assume that weights of males are normally distributed with a mean of 180 lb and a standard deviation of 29 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 152 lb. b. Find the probability that a sample of 29 randomly selected adult males has a mean weight greater than 152 lb. c. What do you conclude about the safety of this elevator? a. The probability that 1 randomly selected adult male has a weight greater than 152 lb is ☐ (Round to four decimal places as needed.)
