At a university approximately 12% of freshman do not return as sophomores. In a freshman class of 2500 students, determine the probability that 290 to 320 (inclusive) students do not return. Give your answer in 3 decimal places. (b) For a chi-squared distribution, find k when sample size is 30. P(k < X2 < 45.72) = 0.925
