Question:

The following data are from a simple random sample: 5, 8, 10, 7, 10, 14. What is the point estimate of the population mean?

Options:

8.5

9

9.5

10

Correct Answer:

9

Explanation:

The correct answer is Option (2) → 9

Given sample data is 5, 8, 10, 7, 10, 14 and n = 6.

The point estimate of population mean is sample mean.

$∴\bar x=\frac{Σx_i}{n}=\frac{5+8 +10 + 7 + 10 + 14}{6}$

$=\frac{54}{6} = 9$
