The Newport Health Clinic experiments with two different configurations for serving patients. In one configuration, all patients enter a single waiting line that feeds three different physicians. In another configuration, patients wait in individual lines at three different physician stations. Waiting times (in minutes) are recorded for 10 patients who are randomly selected from each configuration.
Single line: 65, 66, 67, 68, 71, 73, 73, 77, 77, 77
Multiple lines: 42, 54, 58, 62, 67, 77, 77, 85, 93, 100
Which formula should you use to calculate the variances of the waiting times for each group?

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
