Students’ scores on a test are normally distributed with mean 65 and standard deviation 20. however, the professor discovered that some questions were defective, so the professor decided to adjust the scores by subtracting each student’s score by 0.8, then multiplying by 1.1. find the sum of the first and second raw moments of the adjusted score.

n

step-by-step explanation:

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
