Step-by-step explanation:
<h3>divide 19.4 by 2</h3>
The estimated portion of light bulbs that last more than 500 hours will be
x=∑xn=224/430=0.521=52.1%
<span>The answer is 50.5.
Since X will consist of a random selection of the numbers from 1 to 100, the mean will be the middle of the set of numbers from 1 to 100 (so between 50 and 51). Imagine the set of whole numbers 1 to 100. To calculate the mean, we have to sum all the numbers, then divide by n=100. That gives 50,500/100= 50.5.</span>
