What is | -7.9 ?<br> help

Tamiku [17]

I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!

Answer:

No, this result is not surprising. It is a little bit more than one standard deviation above 20%

Step-by-step explanation:

Proportion of each color in the population (p) = 0.20

Sample size (n) = 20 Skittles

The standard deviation of a sampling distribution is determined by:

$\sigma = \sqrt{\frac{p*(1-p)}{n}}\\\sigma = \sqrt{\frac{0.20*(1-0.20)}{20}}\\ \sigma =0.089$

The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
