Question

A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Felicia read that spinning-rather than flipping-a US penny on a flat surface is not fair, and that spinning a penny makes it more likely to land showing tails. She spun her own penny 100 times to test this, and the penny landed showing tails in 60% of the spins. Let p represent the proportion of spins that this penny would land showing tails. What are appropriate hypotheses for Felicia's significance test? Choose 1 answer: H:p = 50% @ H.:p> 50% H: p = 50% H:p < 50% © Ho: p = 60% H:p> 60% H, :p = 60% Hp < 60%

Answer 1

option A)

Ho :   p = 50%
Ha :   p > 50%
