A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 50 milligrams. You want to test this claim. During your tests, you find that a random sample of thirty 12-ounce bottles of cola has a meancaffeine content of 48.6 milligrams. Assume the population is normally distributed and the population standard deviation is 6.1 milligrams. At a = 0.09, can you reject the company's claim?

In a survey, the mean weight of 1005 rats was calculated to be 132 gr. The standard deviation of the observation was found to be s=3 gr. Determine at least how many of the surveyed rats have a weight between 124.5 and 139.5 gr.
The average number of strawberries that come in a pint is 27.9, with a standard deviation of 7.8. Assume that the number of strawberries in a pint is normally distributed. What percentage of pints would have 31 strawberries or more? Enter your answer as a percent rounded to one decimal place.
Almost all medical schools require applicants to take the Medical College Admission Test (MCAT). To estimate the mean score of those who took the MCAT at WSSU, you will obtain the scores of an SRS of students. The scores follow a Normal distribution, and from published information you know that the standard deviation is 6.5. Suppose that (unknown to you) the mean score of those taking the MCAT at WSSU is 25.0. If you choose one student at random, what is the probability that the students scores is between 20 and 30?
