Libby just got her work schedule for next week and she has less hours than normal. She wonders if everyone's (all 124 employees') hours were cut. She texts 10 of her coworkers and asks, "Do you have less hours than normal next week?" 7 reply 'yes' and 3 reply 'no'. 7/10 = 0.7 = 70% so Libby estimates that 70% of the employees have less hours than normal next week. Is that 70% number a parameter or a statistic AND how do you know?
