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
The point estimate of the population mean is the sample mean:
\( \displaystyle \bar{x} = \frac{6 + 8 + 11 + 9 + 15 + 17}{6} \)
\( \displaystyle = \frac{66}{6} = 11 \)
