4 120
5 202
6 195

Answer: The approximate population mean for student applications (in thousands) is 214.

Explanation:

Since we have given that

Semester Student applications (in thousands)

1 106

2 137

3 285

4 120

5 202

6 195

7 327

8 139

9 307

10 318

11 212

12 217

As we know the formula for Population mean i.e.
\mu=(\sum x_i)/(N)

So, we get that


\mu=(106+137+285+120+202+195+327+139+307+318+212+217)/(12)\\\\\mu=213.75\\\\\mu\approx 214

Hence, The approximate population mean for student applications (in thousands) is 214.
