There are eight multiple-choice questions on an exam, each question having five choices (A, B, C, D, or E). Suppose the student guesses on each question (Note: there is only one correct answer per question). a) Find the probability that the student get exactly 3 correct answers. b) Find the probability that the student get at least one correct answer. c) Find the mean and standard deviation of correct answers obtained by a student

In recent years, there has been increasing concern about health effects of computer terminals. It is know that the miscarriage rate under general conditions is about 15%. A random sample of 700 pregnant women working with a computer 1 to 20 hours per week was taken. For this sample, there were 125 miscarriages. a) We wish to test the hypothesis that “short-term exposure (e.g., 1 to 20 hours per week) to computer terminals increases the rate of miscarriages”. State the appropriate hypotheses. b) Using a significance level of 0.05, test the hypotheses in part (a).

A quality control engineer would like to estimate the mean fill amount of a certain bottle-filling machine to within 0.05 liter. If we assume that the population standard deviation is 0.17 liters, how large of a sample is needed to estimate m with 95% confidence?
