Suppose that in a certain large city, the mean 100 meter dash time for male high school seniors was reported to be 13.3 seconds with a standard deviation of 1.9 seconds. We may assume that the population is normally distributed. c) What is the probability that 35 male high school seniors selected at random will have a mean 100 meter dash time between 13 seconds and 14 seconds?

Suppose that the body lengths of adult male crested porcupines in a certain region in the U.S. are normally distributed with a mean of 73.1 cm and a standard deviation of 5.8 cm. if an adult male crested porcupine is randomly selected from this region, what is the probability that its body length lies between 70 and 75 cm?
Suppose the average amount of money that people spend on their pets per month is 47 dollars, with a standard deviation of 6 dollars. For a sample of 36 people, final the average amount of money spent on pets that defines the bottom 30% in the distribution.For a sample of 36 people, what is the probability for this sample’s mean to be higher than 50 dollars.
To become an actuary, it is necessary to pass a series of 10 exams, including the most important one, an exam in probability and statistics. An insurance company wants to estimate the mean score on this exam for actuarial students who have enrolled in a special study program. They take a sample of 8 actuarial students in this program and find the mean of the sample is 6.0 with standard deviation of the sample 2.0. This sample will be used to calculate a 95% confidence interval for the mean score for actuarial students in the special study program. A 95% confidence interval for the mean score of actuarial students in the special program is from ________ to ________. Question 17 options: 1) 3.52 to 8.47 2) 4.69 to 7.31 3) 4.66 to 7.34 4) 4.33 to 7.67
