A normal distribution has a standard deviation equal to 33. What is the mean of this normal distribution if the probability of scoring above x = 213 is 0.0228? (Round your answer to one decimal place.)

According to national data, about 15% of American college students earn a graduate degree. Using this estimate, what is the probability that exactly 35 undergraduates in a random sample of 200 students will earn a college degree? Hint: Use the normal approximation to the binomial distribution, where p = 0.15 and q = 0.85. (Round your answer to four decimal places.)
