A standard normal distribution has a mean of 0 and standard deviation of 1. This is also known as the z distribution.Find the multiplier for a 99% confidence interval for a mean using a t distribution with 37 degrees of freedom.

The calculator will automatically find this value for you. This tells us that the cumulative probability is 0.78300. This is the area to the left of the F statistic in the F distribution. Typically we're interested in the area to the right of the F statistic, so in this case the p-value would be 1 - 0.78300 = 0.217.StatKey. to accompany Statistics: Unlocking the Power of Data. by Lock, Lock, Lock, Lock, and Lock.
