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:

12

The correct answer is Option (1) → 12

$\text{Sample size }=6.$

$\text{Point estimate of population mean }=\bar{x}=23.$

$\text{Sum of observations }=6\cdot23=138.$

$15+23+x+37+19+32=138.$

$126+x=138.$

$x=12.$
