Five identical scales are labeled from 1 to 5. We know that for each M = 1,2,3,4,5 the scale with label M adds M kg to each weight. The labels are then removed and the scaled are shuffled. A bag is weighed on each scale, producing the following measures in kg:9,10,11,12,13. How many kg does it weigh? (A) 7 (B) 8 (C) 9 (D) 10 (E) 11

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision.
