Question

The weight gain for college freshman is normally distributed with an average of 7 pounds and a standard deviation of 1.2 pounds. If a college freshman is randomly selected, what is the probability that the student's weight gain is more than 10 pounds? ROUND to the nearest THOUSANDTHS place.

Answer 1

Given :- D Let given that the weight gain for College freshman is normally distributed with an average = 7 * Tuen Standard deviation - 1.2 Now, fornula ż= ( x-mean) / Standard deviation z- X-M

NOW 7 => P(x>10) = P(27(10-7)/1-2) p (2> 2.5) 1-p(222.5) - - 1-0.9937 903 = 0.0062
