Given the standardized normal distribution with a mean of 0 and a standard deviation of 1 what is the probability that a.) Z is between -1.57 and 1.84 b.) Z is less than 1.08 c.) Z is less than -1.57 What are the z scores that mark the middle 95% of this distribution w...
aThe question arises as to what normal distribution; that is, a normal distribution with what mean and what standard deviation? Since all estimators have an identical form (a difference of averages), the standard deviations, though unknown, will in fact be the same under the assumption of cons...
The standard deviation of a data set is a measurement of how close, in aggregate, its values are to the mean. The baseline from which this distance is measured is the mean of the data set. In short, a lower stan...
