An organic farmer wanted to find out how many eggs a typical hen lays during 1 month. She chose 8 hens at random from the 60 hens she has, then recorded the number of eggs each of the 8 hens laid.

Number of eggs: 9, 9, 8, 11, 11, 12, 12, 8

What is an estimate of the mean number of eggs laid in the population of 60 hens?

Enter your answer in the box.

Respuesta :

First, you add them all together, and divide them by the number of quantities there are, so:
9+9+8+11+11+12+12+8= 80. Then you divide it by 8 (how many numbers there are) to get 10!
If you are doing an estimate, then you need to look at the numbers to see kinda what they are around.  This set of data seems to be revolving around the number 10 because there are 4 above and 4 below.  So I would put down 10 for my answer.
