(Experimental Probability MC)A fair 6-sided die is rolled 360 times. What is a reasonable prediction for the number of times the event of landing on an odd number will occur?

(08.06 LC) Carter wants to know if warming up will help runners sprint faster. Thirty track and field athletes volunteered to participate in his study. He randomly assigns 15 athletes to warm-up for 10 minutes. All 30 participants sprint the same distance. He calculates the mean for each group and determines that the mean for the warm-up group was 10.7 seconds, and the mean for the other group was 13.2 seconds. To test the difference of means he re-randomized the data 54 times, and the differences are plotted in the dot plot below. What can Carter conclude from his study?

(08.05 MC) A hairdresser owner gives a survey to all of her customers asking them to rate the quality of the service they received. She then keeps track of how many customers return to the salon during the next six months. Last year, the results showed that of the customers who reported high quality service, 95% returned. What conclusion can be drawn from this study?

(08.03 LC) Lazar drives to work every day and passes two independently operated traffic lights. The probability that both lights are green is 0.41. The probability that the first light is green is 0.59. What is the probability that the second light is green, given that the first light is green?

(08.05 MC) A spa owner gives a survey to all of her customers asking them to rate the quality of the service they received.
