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?

Transcribed Image Text:Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 300 times
and 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?
