The sum of the heights of all the students in a class is 1,472in.

1. the mean height is 5ft 4in. How many students atre in the class? (1ft=12in.)

I changed 5ft to 60in. then I added 4in. and divided 2 into 64in. The answer I got was 32 students. Is this correct?

#2. The median height is 5ft2in. How many students are 5ft 2in.or taller? How many are shorter?

I changed 5ft to 60in then added 2in and got that 62 students are taller. After, I subtracted 2in. from 60 and got 58 students are shorter. Is this correct? PLEASE HELP!!!!

Changing 5 ft 4 inches to 64 inches is an excellent first step.

Then, remember that

average height = total of heights / number of students

So, if you let n = number of students,

64 = 1472 / n

Multiply both sides by n:

64n = 1472

Now...you should be able to find n.

Once you know the number of students in the class, you should remember that the median divides the data into two equal parts. So you should be able to figure out how many students are at or above the median height.
