Explanation / Answer

Solution:

Go to data analysis>Dscriptive statistics:

mean=50.185

median=49.5

mode=43

mean is not equal to median

and not equal to mode

Distribution is positively skewed.

Skewness=positive coeffiicent

MAx time it takes 99 minutes

min time is 0 minutes

Range=mx-min=99-0=99

Minutes_to_Task Mean 50.185 Standard Error 1.434413 Median 49.5 Mode 43 Standard Deviation 20.28567 Sample Variance 411.5083 Kurtosis -0.44174 Skewness 0.01281 Range 99 Minimum 0 Maximum 99 Sum 10037 Count 200
