A SRS of 25 recent birth records at the local hospital was selected. In the sample, the average birth weight was x-bar = 119.6 ounces. Suppose the standard deviation is known to be σ = 6.5 ounces. Assume that in the population of all babies born in this hospital, the birth weights follow a Normal distribution, with mean μ. Based on the 25 recent birth records, the sampling distribution of the sample mean will be

A simple random sample of electronic components will be selected to test for the mean 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.
