The following data are from a simple random sample: 6, 8, 11, 9, 15, 17, then the point estimate of the population mean is
Answer & explanation
Correct answer: option 3
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.
