Answer:
Mean of their time
= sum of all observations / total number of observations
=10+7+13+20+15/5
=65/2
=32.5 hours
Median of their work time
= number of observations +1/ 2(this formula is used for odd number of observations)
=5+1/2
=6/2
=3rd observation = 13 hours
There can't be any mode for this data as there must be an recurring value for it.
