Step-by-step explanation:

Given the data set of 15 where:

Mean = 7Median = 6Mode = 5The minimum is 1 and the maximum is 10

As per given we conclude

The set will have 7 numbers before 6 and 7 numbers afterSum of 15 numbers is 15*7 = 105The most used number is 5

a) Possible set is:

1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10

b) Add number 20, the set will be:

1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10, 20

The mean is different as we have now more numbers with different sum:

(105 + 20)/(15 + 1) = 125/16 = 7.8125

The median is different now and moves to the right as 20 added to the far right:

(6 + 9)/2 = 7.5

The mode stays same as still most used number is 5:

5

Ithink it would be 160 people
