The following data are from a simple random sample: 5, 8, 10, 7, 10, 14. What is the point estimate of the population mean?
Answer & explanation
Correct answer: option 2
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.
$∴\bar x=\frac{Σx_i}{n}=\frac{5+8 +10 + 7 + 10 + 14}{6}$
$=\frac{54}{6} = 9$
