Answer 1

Answer:

RYAN

Step-by-step explanation:

6+7+8+9+10=40

40 divided by 5= 8

mean is all numbers added together divided by amount of numbers

Answer 2

The average number of hours that adults spend working each day is; 8 hours and Ryan is correct because he got the average of 8 right.

How to calculate the mean from a sample of data?

The mean is gotten from the formula;

x' = ∑x/n

Number of hours of work per day are; 6, 7, 8, 9 and 10

Thus;∑x = 6 + 7 + 8 + 9 + 10

∑x = 40

Mean is; x' = 40/5

x' = 8

Since ryan concluded that the average is 8 hours, then we can say that Ryan is correct.
