In an all boys school, the heights of the student body are normally distributed with a mean of 71 inches and a standard deviation of 4.5 inches. Using the empirical rule, determine the interval of heights that represents the middle 95% of male heights from this school.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

35=5×77=7×1when we simplify 7 by 7we will get 5 and 1, 5 divided by 1 is 5
