Company X tested its light bulbs to see how long they would last. On a production line, 2,500 bulbs were taken and tested. The department in charge reported that out of 2,500 bulbs, there were 2,200 bulbs that burnt out after more than 1,500 hours of use. Lucy purchased a light bulb from Company X. What is the likelihood that it will burn for more than 1,500 hours? Write your answer in decimal form.(1 point)
The likelihood that Lucy's light bulb will burn for more than 1,500 hours is 0.88.
This is because out of the 2,500 bulbs tested, 2,200 burnt out after more than 1,500 hours.
So the probability of a bulb from Company X burning out after more than 1,500 hours is 2,200/2,500 = 0.88.
The likelihood of a light bulb from Company X lasting more than 1,500 hours can be calculated by dividing the number of bulbs that lasted more than 1,500 hours (2,200) by the total number of bulbs tested (2,500).
Likelihood = 2,200/2,500 = 0.88 or 88%
So, the likelihood that Lucy's light bulb will last more than 1,500 hours is 0.88 or 88%.
To calculate the likelihood that Lucy's bulb will burn for more than 1,500 hours, we need to find the proportion of bulbs in the sample that burned out after more than 1,500 hours.
Proportion = Number of bulbs that burned out after more than 1,500 hours / Total number of bulbs
In this case, the number of bulbs that burned out after more than 1,500 hours is 2,200, and the total number of bulbs is 2,500.
Proportion = 2,200 / 2,500
Calculating this proportion, we get:
Proportion = 0.88
Therefore, the likelihood that Lucy's bulb will burn for more than 1,500 hours is 0.88 or 88% (in decimal form).
To find the likelihood that Lucy's light bulb will burn for more than 1,500 hours, we can look at the proportion of bulbs that burnt out after more than 1,500 hours in the test conducted by Company X.
In the test, out of 2,500 bulbs, there were 2,200 bulbs that burnt out after more than 1,500 hours. So, the proportion of bulbs that burnt out after more than 1,500 hours is:
Proportion = Number of bulbs that burnt out after more than 1,500 hours / Total number of bulbs tested
= 2,200 / 2,500
= 0.88
Therefore, the likelihood that Lucy's light bulb will burn for more than 1,500 hours is 0.88 or 88% (in decimal form).
