A simple rаndоm sаmple оf electrоnic components will be selected to test for the meаn lifetime in hours. Assume that component lifetimes are normally distributed with population standard deviation of {sd} hours. How many components must be sampled so that a 99% confidence interval will have margin of error of {m} hours? 50% 70% 80% 90% 95% 98% 99% 99.9% z* 0.674 1.036 1.282 1.645 1.960 2.326 2.576 3.291 Write only an integer as your answer.
