Explanation / Answer
1. By using Excel’s statistical function, “STDEV”, the standard deviation is 29.3619651930861. Hence the correct option is A.
2. By using Excel’s statistical function, “VAR, the variance is 862.125. Hence the correct option C.
Mean can only be equal to median when the data is symmetrically distributed. Here data is random and therefore median will not be equal to mean.
