The probability that a student gets a multiple-choice question correct on a statistics test is 0.80. Use the normal approximation to the binomial method to find the probability that a student gets a B or a C (21-26 correct answers) on a test with 30 questions. To calculate the probability, what is the upper and lower bounds of the normal approximation
