The lengths of Atlantic Croaker Fish are normally distributed with mean of 10 inches and a standard deviation of 2 inches. An Atlantic croaker fish is randomly selected. Find the probability that the length of the fish is less than 7 inches. If 200 Atlantic croakers are randomly selected, about how many would you expect to be shorter than 7 inches? Round your answer to the nearest whole number. Find the 60th percentile for the length of Atlantic croakers

Suppose scores on an examination are normally distributed. If the examination scores have a mean 60% and a standard deviation of 15%, what is the probability that a student who takes the examination will score between 80% and 90%? I need answer ASAP. Thank you!

The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. a. Find the probability of a pregnancy lasting 308 days or longer. b. If the length of pregnancy is in the lowest 3%, then the baby is premature. Find the length that separates premature babies from those who are not premature. Click to view page 1 of the table. Click to view page 2 of the table. a. The probability that a pregnancy will last 308 days or longer is (Round to four decimal places as needed.) b. Babies who are born on or before days are considered premature. (Round to the nearest integer as needed.)

A mean of 200 and a standard deviation of 50. Find P60, the score which separates the lower 60% form the top 40%.

z Scores LeBron James, one of the most successful basketball players of all time, has a height of 6 feet 8 inches, or 203 cm. Based on statistics from Data Set 1 “Body Data” in Appendix B, his height converts to the z score of 4.07. How many standard deviations is his height above the mean?

The distances golf balls travel under laboratory testing conditions are normally distributed. The mean is 312 yards. The probability the golf ball travels further than 319 yards is 0.28. Find the probability a randomly selected golf ball travels between 305 yards and 319 yards. Express the answer as a decimal value rounded to the nearest hundredth.
