A major university claimed that the mean number of credit hours that their entire population of undergraduate students took each semester was 13.1. A counselor questioned whether this was true. She took a random sample of 250 undergraduate students, and the mean of that sample of students showed that they completed 12.8 credit hours. The population standard deviation is 1.6. Conduct a full hypothesis test using the p-value approach. Let α = .05.

Determine if the mean credit hours for the sample is significantly different than that of the population.

What formula seems to match what we have been given and what we need to find?

The dean of a university estimates that the mean number of classroom hours per week for full-time faculty is 11.0. As a member of the student council, you want to test this claim. A random sample of the number of classroom hours for eight full-time faculty for one week is shown in the table below. At alphaequals0.05, can you reject the dean's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 11.2 9.8 13.2 8.1 5.4...

To test President Loh’s belief, you analyze data from 29 male students enrolled in BMGT 230/230B this semester and 13 female students enrolled in BMGT 230/230B this semester. a. Assuming equal population variances, if the level of significance equals 0.05 and the one-tail p-VALUE...

You spoke with your instructor and she claimed that the average number of hours that you should study has to be more than 5 hours per week which will help you achieve an above average grade on any subject. She also suggested as a practice that you can test her claim and let her know what your conclusion is. So you decided to contact your peers and gather information to conduct a hypothesis to test your instructors claim. Questions: Contact...

An insurance company knows that in the entire population of millions of homeowners, the mean annual loss from fire is μμ = $100 and the standard deviation of the loss is σσ = $300. The distribution of losses is strongly right skewed: most policies have $0 loss, but a few have large losses. If the company sells 10,000 policies, what is the probability that it can safely base its rates on the assumption that its average loss will be no...

A credit Bureau analysis of undergraduate student credit records found that the mean number of credit cards that an undergraduate carries is 5. There is some evidence that this occurs as credit card companies flood college campuses with prizes and gifts for signing up for the cards. CSU banned these types of initiatives from campus in 2014 and they argue that at CSU a typical undergraduate will have less than 5 cards due to this. You want to determine if...

A university system enrolling thousands of students needs to determine how many credit hours, on the average, each student takes per quarter. From previous studies, the population standard deviation is known to be 2.3 credit hours per quarter. Suppose the administration wanted to estimate the mean to within 0.1 hours with 95% confidence. How large a sample would they need to take?
