The number of hours a battery lasts before failing varies from battery to battery. The distribution of Failure times Fallows an Exponential distribution, which is strongly skewed to the right. the central limit theorem says that A) as we look at more and more batteries, their average failure time gets ever closer to mean for all batteries of this type. B) the average failure time of a large number of batteries has a distribution of the same shape (strongly skewed) as the distribution for individual batteries. C) the average failure time of a large number of batteries has a distribution that is close to Normal.

What is the value of r of the geometric series?

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
