You want to know the mean height of high school students in a school district. You randomly survey 10 high school students in 6 different schools. Your results are shown in the table. Find the mean of each sample. Then use the first and third quartiles of the sample means to describe the actual mean height of the students. Write each answer as a decimal.

Heights of Students (inches) Mean
1: 67, 66, 70, 65, 62, 66, 73, 58, 76, 60
2: 61, 67, 69, 68, 69, 63, 65, 61, 63, 68
3: 67, 64, 65, 66, 71, 72, 67, 69, 60, 65
4: 69, 63, 68, 65, 63, 67, 62, 65, 64, 74
5: 72, 69, 61, 65, 66, 71, 68, 68, 63, 66
6: 62, 62, 70, 68, 71, 64, 60, 66, 64, 67
