The following data is from a simple random sample :
15, 23, x, 37, 19, 32
If the point estimate of the population mean is 23, then the value of x is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 12
$\text{Sample size }=6.$
$\text{Point estimate of population mean }=\bar{x}=23.$
$\text{Sum of observations }=6\cdot23=138.$
$15+23+x+37+19+32=138.$
$126+x=138.$
$x=12.$
