inning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 300 times d got 134 heads. We wish to find how significant is this evidence against equal probabilities. a. What is the sample proportion of heads? Round to 3 decimal places. b. 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? O Ho: p = 0.5 Ha: p - 0.5 O Ho: p = 0.5 Ha: p > 0.5 O Ho: p = 0.5 Ha: p < 0.5 O Ho: P - 0.5 Ha: p = 0.5
