    During a semester, a class of n=50 students took two exams: a midterm and final. The mean source for the midterm exam is 80 points with the standard deviation of 6 points. The mean score for the final exam is 85 points with the standard deviation of 10 points. The calculated coefficient of correlation (r) for the two scores is 0.75. Q. Calculate the value of SSE (sum of square of error) using the above information.

    Suppose there are n students in a class. Assume n ≤ 365, and all possible sequences of n birthdays are equally likely. We also assume that the birthday of a student is equally likely to be any one of the 365 days of the year (i.e., ignore leap years or seasonal variation in birth rate). (a) What is the probability that all n students have different birthdays? (b) Calculate this probability numerically when n = 23, 45, 65 and 70....
