The Standard Normal Distribution • The probability values expressed in terms of standard deviations, as in the previous two slides, are true no matter what the standard deviation or mean are. • Consequently, if we know values for the normal distribution with mean 0 and standard deviation 1, we know ...

... How to find areas with a nonstandard normal distribution: 1. Sketch a normal curve, label the mean and the specific x values, then shade the region representing the desired probability 2. For each relevant value x that is a boundary for the shaded region, use the formula to convert that value to t ...

... The p-value above was calculated by a spreadsheet. If you are using tables, you will have a hard time coming up with a precise p-value, but you will be able to produce bounds. In our case, the t-score of 1.42118 lies (in the row for 32 degrees of freedom) between 1.694 (probability 0.05) and 1.309 ( ...
