Two groups of students are doing a coin flip experiment. Group 1 flips a quarter 100 times and gets 40 heads and 60 tails. Group 2 flips a nickel 200 times and gets 95 heads and 105 tails. For group 1 the experimental probability of getting tails is 0.6 and for group 2 the experimental probability of getting tails is 0.525. Which statement is true?
