Question

Spinning a coin, unlike tossing it, may not give heads and tails in equal proportions. I spin a penny 300 times and get 132 heads. We want to know if we have significant evidence that the coin is not fair.

What is the sample statistic?

Round to 3 places.
Which symbol is used for the statistic in this problem?
- ˆpp^
- μμ
- ππ
- ¯xx¯
Which hypotheses do we want to test?
- H₀: ππ = 0.5
  H_Aππ < 0.5
- H₀: ππ = 0.5
  H_A: ππ ≠ 0.5
- H₀: ππ ≠ 0.5
  H_A: ππ = 0.5
- H₀: μμ = 0.5
  H_A: μμ ≠0.5
