The mean height of women in a country (ages 20-29) is 64.3 inches. A random sample of 70 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume o = 2.86. The probability that the mean height for the sample is greater than 65 inches is (Round to four decimal places as needed.)
The average student loan debt for college graduates is $25,750. Suppose that that distribution is normal and that the standard deviation is $10,350. Let X = the student loan debt of a randomly selected college graduate. Round all probabilities to 4 decimal places and all dollar answers to the nearest dollar. Find the probability that the college graduate has between $22,700 and $30,000 in student loan debt. (------) The middle 20% of college graduates' loan debt lies between what two numbers?

What is the probability that the total of two randomly chosen numbers exceeds 3, where the first number is chosen from a uniform distribution between 0 and 2, and the second number is selected from an exponential distribution with a mean of 1?
Suppose that the only information you have is that in the last 90 days a total of 27,000 students visited. Can you say anything about the probability that more than 500 students visit on a given day? Suppose that you got some additional information saying that the standard deviation of students visiting per day is 50 students. Can you say anything more precise about the probability that more than 500 students visit on a given day?
