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

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

Step-by-step 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. $\mu=\dfrac{\sum x_i}{N}$

So, we get that

$\mu=\dfrac{106+137+285+120+202+195+327+139+307+318+212+217}{12}\\\\\mu=213.75\\\\\mu\approx 214$

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

Answer 2

The correct answer is

214
