The marks obtained by five students in a test of Applied Mathematics carrying 100 marks are 49, 58, 67, 92, 99. Then the point estimate of the population mean is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 73 **
Data: $49,\;58,\;67,\;92,\;99$
Point estimate of population mean = sample mean.
$\displaystyle \bar{x}=\frac{49+58+67+92+99}{5}$
$49+58=107$
$107+67=174$
$174+92=266$
$266+99=365$
$\displaystyle \bar{x}=\frac{365}{5}=73$
Point estimate of population mean = 73
