Amanufacturer makes lightbulbs and claims that their reliability is 98 percent. reliability is defined to be the proportion of nondefective items that are produced over the long term. if the company's claim is correct, what is the expected number of nondefective lightbulbs in a random sample of 1,000 bulbs?

The expected number of nondefective lightbulbs is 980 out of a random sample of 1,000 bulbs.

Explanation:

Hi, if the company is right, this is the operation that we need to do.

So, we are expecting 980 working bulbs out of a sample of 1,000

Best of luck

there was no passage listed but using the process of elimination i'd say it was d. the high economy would do the opposite. i don't see how low prices would affect it. high unemployment is possible but i feel d is the better answer.

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!
