Question

On day 1, Rakesh worked 8 hours and tracked his sales per hour. He made 4, 6, 8, 1, 3, 9, 7, and 8 sales,
On day 2, Rakesh made 10 more sales than he did on day 1.
What is the increase in the mean sales per hour for the second day compared to the first?

Answer 1

The increase in the mean sales per hour for the second day when compared with the mean sale on the first day is 1.25.

What is the increase in the mean sales?

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean sales on the first day = sum of the numbers / total number

(4 + 6 + 8 + 1 + 3 + 9 + 7 + 8) / 8 = 46/8 = 5.75

Mean sales on the second day = (46 + 10) / 8 = 7

Change in the mean = 7 - 5.75 = 1.25
