A pathology lab does not deliver 10 percent of the test results in a timely manner. Suppose that in a given week, it delivered 351 test results to a certain hospital. Assuming that the test results are independent from one another, determine the following probabilities: np = n(1 − p) = = Both these values are bigger than Can we use the normal approximation to the binomial distribution (type YES or NO)? (a) At least 39 test results were not delivered in a timely manner. (b) Between 37 and 44 (inclusive) test results were not delivered in a timely manner. (c) Under 47 test results were not delivered in a timely manner.
