Online Program15 women went on a 6 month long weight loss program. They recorded their weights, in pounds, before and after completing the program. The results can be seen in the dot plots below (all weights have been rounded to the nearest 10 pounds).
Let \(R_1\) and \(\sigma_1 \)be the range and standard deviation, respectively, of the weights before beginning the weight loss program, and let \(R_2\) and \(\sigma_2\) be the range and standard deviation, respectively, of the weights after completing the weight loss program. Which of the following is true?
