Answer 1

Mean is konwm as the average and it is the ratio of the sum of samples to the sample size.

Given the data for adult brets

80 80 130 135 75

Sample size = 5

Sum of variables =80+80+130+135+75

Sum of variables = 500

Mean age of bret = 500/5

Mean age of bret is 100

Total numer of adult bret will be 500

Given the hours used as 1,23,4,5

Sample size = 5

sum of variables = 1+2+3+4+5 = 15

Mean of time = 15/5 = 3hours

Since Dan concludes that adults spend a mean of 3 hours each day doing, ttyer leisure and sports activities, therefore Dan us correct
