A company produces light bulbs whose life follows a normal distribution, with mean (1300+R) hours and standard deviation (50+R) hours. If we choose a light bulb randomly a. What is the probability that its lifetime will be less than 1600 hours? b. What is the probability that its lifetime will be more than 1850 hours? c. What is the probability that its lifetime will be between 1280 and 1740 hours? d. What is the lifetime in hours that R% of the bulbs exceed?

Concept explainers

Power Operation

Power operation is topic of algebra in Math. It is use to represent repeated multiplication. Very big number and very small number can be easily express using power operation. Power operation is useful in many fields. In space engineering, it helps in representing the distance or size of particular heavenly body. In medical field, it is used to represent very small size. In medical field it helps to mention size of bacteria or virus.

Exponents

The exponent or power or index of a variable/number is the number of times that variable/number is multiplied by itself.

Although the two lines are exactly the same length, the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line.
