Question

The weight of adults Male beagles are normally distributed, with a mean of 25 pounds and a standard deviation of 4 pounds.

The probability that a randomly selected beagle weighs between 15 pounds and 33 pounds is closest to?

Answer 1

There is a 95.6% chance that the weight will fall within this range.

Explanation:

This is because the extremes that are given are roughly two standard deviations from the mean. To be outside of that, there is only 2.2% likelihood to be higher and another 2.2% to be lower. When we subtract these two from 100%, we get our probability.

100% - 2.2% - 2.2% = 95.6%
