A t-distribution looks a lot like a normal distribution, but it is a bit more spread out than a normal distribution with more observations in the "tails." fewer in the middle. To determine whether aresult is out in the tail of a normal distribution, we use a standardized statistic of 2 as our guideline. We can use the same guideline for r-distributions. Suppose, however, the standardized statistic of 2
was a precise rule for a normal distribution. Would the corresponding precise rule for a t-distribution use a number that was more or less
than 2? Explain.
