Record the value of each mean you calculated on a separate post-it note. Use your post-it notes to plot your four means on the class display. Examine the class distribution of means, and record it below. Use the class means to estimate the probability of observing a mean as low or lower than our observed sample mean. Record your estimate here. What would you conclude about your hypotheses based on this estimate? Compare and contrast this probability and your conclusions with your probability and conclusions from #6. With which estimate are you more confident for drawing conclusions about recent petroleum engineering graduates’ starting salaries and why? How many means did you record on your dotplot in #8? Randomizing for Significance
