Question

Each night, Abby recorded how many pages of a book she read before going to bed. Her data is as follows: 7, 9, 10, 6, 8, 12, 5, 11, 48, and 13.

What is the mean number for pages she read each night?

What is the median?

Answer 1

mean = 12.9

median = 9.5

Explanation:

mean = sum of all observations / total no. of observations

= 7+9+10+6+8+12+5+11+48+13 / 10

=129 / 10

= 12.9

median = middlemost no. after arranging in ascending order

= 5,6,7,8,9,10,11,13,48

=9 and 10

=9+10 / 2

= 19 / 2

= 9.5
