    What have you tried?

    Where are you stuck?

    I was wondering if it's something to do with normal distribution or central limit theorem but honestly, I have no idea at all on how to solve this question

    I tried to approximate normal to binomial and out of groups of 20 flips, for the first set, I got 10, 6, 9, 8, 8, 11, 11, 10, 9, 11 "0"s and for the second set, I got 12, 9, 9, 9, 10, 12, 10, 12, 11, 11 "0"s.

    Am I on the right track?
