Question

the following table shows the number of miles a hiker walked on a trail each day for 6 days.

day	number of miles
2	5
3	7
4	2
5	9
6	8

what was the mean number of miles the hiker walked for the 6 days?

options:
a 3.5
b 4.5
c 6.5
d 7.5
e 8

Explanation:

Step1: Sum the miles

The miles for each day are 8, 5, 7, 2, 9, 8. So the sum is $8 + 5 + 7 + 2 + 9 + 8 = 39$.

Step2: Calculate the mean

The mean is the sum divided by the number of days (6). So the mean is $\frac{39}{6} = 6.5$.

Answer:

C. 6.5
