Suppose that a certain college class contains 45 students. Of these, 26 are sophomores, 25 are chemistry majors, and 7 are neither. A student is selected at random from the class.
(a) What is the probability that the student is both a sophomore and a chemistry major?(b) Given that the student selected is a chemistry major, what is the probability that he is also a sophomore?
Standardized measures seem to indicate that the average level of anxiety has increased gradually over the past 50 years. In the 1950s, the average score on the child manifest anxiety scale was µ=15.1. A sample of n=16 of today's children produces ..
Use these data to obtain a 90% confidence interval estimate for the mean starting monthly salary, µ, of all recent graduates with bachelor's degrees in marketing from this university.

If we know that the length of time it takes a college student to find out a parking spot in library parking lot follows a normal distribution with a mean of 3.5 minutes and a standard deviation of 1 minute
Take a confidence interval for the difference in the average of renting between the first andthird hotel.
Identify the sampling distribution to be used: the standard normal distribution or the Student's t distribution. Find the critical value(s).
In the belief that Statistics is too hard, a student claims that the mean score on a final exam is less then 70. 15 scores will be chosen at random to test this claim.
hat is sampling error? Could the value of the sampling error be zero? If it were zero, what would this mean? List the reasons for sampling. Give an example of each reason for sampling.
