Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 300 times and got 122 heads. We wish to find how significant is this evidence against equal probabilities. What is the sample proportion of heads? Round to 3 places. Heads do not make up half of the sample. Is this sample evidence that the probabilities of heads and tails are different?Take p to be the probability of getting heads in a spin of a penny. Which hypotheses do we want to test?
