Question

genetic factors and growth quick check
you weigh 5 kittens all from the same litter and get the following data (in pounds):
1.05, 1.2, 1.15, 1.2, 1.4.
calculate the average weight of the kittens, in pounds.
(1 point)
1.2
1.15
1.3
1.0

Explanation:

Step1: Sum up the weights

$$1.05 + 1.2+1.15 + 1.2+1.4$$
$$=(1.05 + 1.15)+(1.2 + 1.2)+1.4$$
$$=2.2+2.4 + 1.4$$
$$=6$$

Step2: Calculate the average

The formula for the average $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $n = 5$ (the number of kittens) and $\sum_{i=1}^{n}x_{i}=6$.
So, $\bar{x}=\frac{6}{5}=1.2$

Answer:

1.2
