The point estimate for the mean number of sales of cars for the following data
103, 140, 92, 115, 110, is :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 112
The point estimate of the population mean is the sample mean:
\( \displaystyle \overline{x} = \frac{103 + 140 + 92 + 115 + 110}{5} \)
\( \displaystyle = \frac{560}{5} = 112 \)
