Question

The table shows the total number of student applications to universities in a particular state for a random sample of 12 semesters.

What is the approximate sample mean for student applications, in thousands?

A. 2,565
B. 32.9
C. 256.5
D. 214

Answer 1

To calculate the approximate sample mean for student applications, in thousands, you can sum up the total number of student applications for the 12 semesters and then divide by 12.

Add up the total number of student applications for the 12 semesters:

106 + 137 + 285 + 120 + 202 + 195 + 327 + 139 + 307 + 318 + 212 + 217 = 2,563

Divide the sum by 12 to get the sample mean:

2,563 / 12 ≈ 213.6

So, the approximate sample mean for student applications, in thousands, is approximately 213.6.

Answer: D. 214
