Find the following:  d. The probability that the student requires at least 45 minutes to complete the quiz. The probability that the student completes the quiz exactly 52 minutes. f. Compute the expected time and the coefficient of variation to complete the quiz. B) Using 95% confidence, how large a sample should be taken to obtain a margin of error for the estimation of a population proportion of .065? Assume that the data are not available for developing the planning value for r
