      t = -4.62, critical value of t < -2.33, p = 0.009. Errors in Hypothesis Testing. Sometimes you will see a reference to Hypothesis Test errors. They are classified as Type I and Type II errors. Note: You set the value of . The value of depends on the difference between the hypothesized mean and the true value of the population mean.
