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 |
73 69 67 91.25 |
73 |
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 |
