Finding P-Values using the t-distribution

Example: Find the P-Value for a left-tailed test with n=27 and test statistic t = -1.500 Remember that the P-Value is the probability of getting a test statistic that is at least as extreme as the one representing the sample data, assuming that the null hypothesis is true. So, in this case, we want to find the P(t < - 1.500) with deg of freedom ... ................
