the sum of the hieghts of all the students in Mrs.Maloneys class is 1,472 in. The mean height is 5ft 4in how many students are in the class? (1ft = 12in)
1472 / 64 = ?
so if the answer is 23 students would the answer to this
the median height is 5ft 2in how many students in mrs. maloneys class are 5ft 2in or taller? worked the same way the answer would be 23 also?
the answer is 23 students
The median height is the height right in the middle. Half of the students are shorter than 5 ft., 2 in. Half are taller than that.
23/2 = 11.5
So 11 are shorter, 11 are taller, and one student is exactly 5 ft. 2 in.
