And actually, it doesn't have to be normal. But I'll just draw it as a normal distribution. So this is the distribution of The observed difference in sample means (10) produced a t statistic of 0.67. We use the t Distribution Calculator to find P(t 0.67) = 0.75. This means we would expect to find an observed difference in sample means of 10 or less in 75% of our samples, if the true difference were actually 7. Therefore, the P-value in this analysis is 0.75.
