Question

A sample of 8 passengers leaving a bus station had the following ages: 18, 18, 26, 20, 34, 43, 51, and 14. Which estimate is the mean age for all passengers at the bus station? ResponsesA= 23 B=23 C= 27 D=27 E= 28 F= 28 G=37

Answer 1

mean = 28

Explanation:

the mean is calculated as

mean =
`(sum)/(count)` =
`(18+18+26+20+34+43+51+14)/(8)` =
`(224)/(8)` = 28

Answer 2

28

Explanation:

To find the mean of the passengers, add up all the ages and then divide by the number of passengers.

( 18+ 18+ 26+ 20+ 34+ 43+ 51+14)/8

224/8

28
