Use the sorted weights of M&Ms from the preceding exercise to find the value of P25. How does the result compare to the value of Q₁?

Data from in Preceding exercise

Listed below are sorted weights (g) of a sample of M&M plain candies randomly selected from one bag. Use the range rule of thumb to estimate the value of the standard deviation of all 345 M&Ms in the bag. Compare the result to the standard deviation of 0.0366 g computed from all of the 345 M&Ms in the bag.
