Question

The table shows the total number of student applications to universities in a particular state over a period of 12 semesters. A random sample of 5 semesters of data is drawn from this population of 12 semesters. What is the approximate population mean for student applications, in thousands?

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

Answer 1

The correct answer is

214

:)

Answer 2

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.
