Question

Company company X tested it's light bulbs to see how long they would last on a production line $2,500 balls were taken and tested the department in charge reported that out of $2,500 bulbs that there were 2,200 bulbs of burnt out after more than 1500 hours of use Lucy purchased a light bulb from company x what is the likelihood that it would burn for more than $1,500 hours right your answer in decimal form

Answer 1

The likelihood that a light bulb from company X will burn for more than 1,500 hours can be calculated using the proportion of bulbs that burned out after more than 1,500 hours in the sample tested.

The proportion of burnt out bulbs after more than 1,500 hours in the sample tested is 2,200/2,500 = 0.88.

Therefore, the likelihood that Lucy's purchased light bulb from company X will burn for more than 1,500 hours is 0.88.
