A brand of frozen green beans lists a weight of 32 ounces on its bag. Because of variability in the manufacturing process, the bags often contain slightly more, or less, than 32 ounces of green beans. An inspector takes a random sample of 25 bags of green beans and records their weights. The weights and their relative frequencies are summarized in the histogram below. A histogram titled Green Beans has actual weight (ounces) on the x-axis, and relative frequency on the y-axis. 31.8 to 31.9, 0.04; 31.9 to 32.0, 0.04; 32 to 32.1, 0.12; 32.1 to 32.2, 0.2; 32.2 to 32.3, 0.36; 32.3 to 32.4, 0.23. Which is a true statement about the bags of green beans in the sample? Twenty percent of the bags have a weight below 32.2 ounces. Sixty percent of the bags have a weight over 32.2 ounces. Eighty percent of the bags have a weight over 32.2 ounces. The interval from 32.3 to 32.4 contains the highest proportion of bags.
