Using the calculator and df = 12.57, P-value = 0.034. (c) If there is no difference between the mean VOT of adults and children, the probability of obtaining a sample mean difference this far or farther from 0 is 0.034. We reject H0. We have convincing evidence that there is a difference in the mean VOT of adults and children.

In other words, the standard deviation of a discrete uniform random variable X can be calculated as follows: For each value xi calculate the difference between xi and the average value . Calculate the squares of these differences. Find the average of the squared differences. This quantity is the variance σ2. Take the square root of the variance.
