Elian heard that spinning a coin on a flat surface-rather than flipping it-made the probability of the coin landingshowing "heads" something other than 50%. To test this theory, he spun a nickel a series of 80 times andobserved 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. He80 spins where each spin had a 50% chance of showing "heads," and he recordedgenerated a sample of n =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:0.350.400.45 0.50 0.550.60 0.65Simulated sample proportions He wants to test Ho : p = 50% vs. Ha : p 50% where p is the true proportion of spins this coin wouldland showing "heads."Based on these simulated results, what is the approximate p-value of the test?Note: The sample result was p = 60%.Choose 1 answer:Ap-value - 0.056Bp-value 0.07p-value 0.08p-value 0.10
