Question
Given that the arithmetic mean and standard deviation of a sample of 15 observations are 24 and 0 respectively. Then which one of the following is the arithmetic mean of the smallest five observations in the data?(a) 0(b) 8(c) 16(d) 24
Step 1
We have a sample of 15 observations with an arithmetic mean of 24 and a standard deviation of 0. A standard deviation of 0 indicates that all observations in the sample are identical. Show more…

The sum of 15 observations of a data is $(434+\mathrm{x})$. If the mean of the data is $\mathrm{x}$, then find $\mathrm{x}$. (1) 25 (2) 27 (3) 31 (4) 33
The arithmetic mean of five observations is $6.4$ and the variance is $8.24$. If three of the observations are $3,4,8$, then find the other two observations. (A) 6,11 (B) 10,7 (C) 8,9 (D) 5,12
