The following data are from a simple random sample: 3, 7 , 4 , 12 , 4 , 12. The point estimate of the population mean is,
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 7
The sample mean \( \bar{x} \) is the point estimate of the population mean μ.
\( \displaystyle \bar{x}=\frac{3+7+4+12+4+12}{6} \)
\( \displaystyle \bar{x}=\frac{42}{6}=7 \)
