Elian heard that spinning a coin on a flat surface-rather than flipping it-made the probability of the coin landing showing "heads" something other than 50%. To test this theory, he spun a nickel a series of 80 times and
observed that p = 60% of the spins landed showing "heads."
To see how likely a sample like this was to happen by random chance alone, Elian performed a simulation. He
generated a sample of n = 80 spins where each spin had a 50% chance of showing "heads," and he recorded
what proportion of spins in the sample showed "heads." He repeated this process for a total of 125 samples.
Here are the sample proportions from his 125 samples:
