The number of hours a battery lasts before failing varies from battery to batter

Question

The number of hours a battery lasts before failing varies from battery to battery. The distribution of failure times for the batteries follows an exponential distribution, which just means the shape of the distribution ls ne normal and is strongly skewed to the right. The central limit theorem says that (circle one letter) . As we look at more and more batteries, their average failure time gets ever closer to the mean for all batteries of this type. the average failure time of a larger number of batteries has a skewed) as the distribution for individual batteries distribution of the same shape (strongly The average failure time of a large number of batteries has a distribution that is close to Normal. s of 100 high school seniors gained an average of r = 12 points in their second attempt
