An experimenter flips a coin 100 times and gets 42 heads. Test the claim that the coin is fair against the two-sided claim that it is not fair at the level α=.01. a) Ho: p = .5, Ha: p ≠ .5; z = −1.60; Reject Ho at the 1% significance level. b) Ho: p = .5, Ha: p ≠ .5; z = −1.60; Fail to reject Ho at the 1% significance level. c) Ho: p = .5, Ha: p < .5; z = −1.62; Fail to reject Ho at the 1% significance level. d) Ho: p = .5, Ha: p < .5; z = −1.60; Reject Ho at the 1% significance level.

a) Ho: p = .5, Ha: p ≠ .5; z = −1.60; Reject Ho at the 1% significance level.
b) Ho: p = .5, Ha: p ≠ .5; z = −1.60; Fail to reject Ho at the 1% significance level.
c) Ho: p = .5, Ha: p < .5; z = −1.62; Fail to reject Ho at the 1% significance level.
d) Ho: p = .5, Ha: p < .5; z = −1.60; Reject Ho at the 1% significance level.
