Question

the term freshman 15 refers to the claim that college students typically gain 15 lb during their freshman year of college. assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of 2.9 lb and a standard deviation of 10.7 lb. find the probability that a randomly selected male college student gains 15 lb or more during his freshman year. what does the result suggest about the claim of the freshman 15?
the percentage of freshmen that gain 15 pounds or more in their first year of university is 12.9%. (round to one decimal place as needed.)
does this percentage suggest the freshman 15 is accurate?
a. no, because the percentage is low. most freshmen males do not gain 15 pounds or more
b. yes, because the percentage is low. most freshmen males do gain 15 pounds or more
c. no, because the percentage is high. most freshmen males do not gain 15 pounds or more
d. yes, because the percentage is high. most freshmen males do gain 15 pounds or more

Explanation:

The percentage of \(12.9\%\) means that only about \(12.9\) out of \(100\) male college students gain \(15\) lb or more. A low percentage (\(12.9\%\) is less than \(50\%\)) indicates that most male college students do not gain \(15\) lb or more.

Answer:

A. No, because the percentage is low. Most freshmen males do not gain 15 pounds or more
