For the past 10 days, she has sampled four batches of the "entrée du jour" and recorded the sodium content per serving. 1) Based on the data that follows, construct the X and R charts. 2) Based on the X and R charts, is the process in control? Why or why not? 3) Given the fact that the sodium content should be between 450 and 520 mg per serving for meal-type products, does the dietitian have a valid concern?
