Question:

The following data are from a simple random sample: 6, 8, 11, 9, 15, 17, then the point estimate of the population mean is

Options:

9

10

11

12

Correct Answer:

11

Explanation:

The correct answer is Option (3) → 11 **

Given sample values: $6,\;8,\;11,\;9,\;15,\;17$

Point estimate of population mean = sample mean.

Sum of values: $6+8+11+9+15+17 = 66$

Number of observations: $6$

Sample mean = $ \frac{66}{6} = 11 $

The point estimate of the population mean is 11.
