Question

Marianne Squirrel teaches a hula dancing class to young squirrels.

13 squirrels showed up to class on Monday,
11 squirrels on Tuesday,
7 squirrels on Wednesday,
10 squirrels on Thursday, and
12 squirrels on Friday.
Find the mean number of squirrels.​

Answer 1

The exact answer is 10.6 squirrels (but since squirrels are discrete objects, we can round this to get 11 squirrels as the mean)

Explanation:

To find the mean, we just add the values of the data points (in this case, the number of squirrels) and then divide the result by the number of data points (in this case 5 corresponding to the 5 days)

So,

the mean is,

M = (13 + 11 + 7 + 10 + 12)/5

M = 53/5

M = 10.6 Squirrels

Or after rounding,

the mean number of squirrels is 11
