A coin is flipped 100 times, and 42 heads are observed. Find a
99% confidence interval of π (the true population proportion of
getting heads) and draw a conclusion based on the collected data.
Hint: Choose the best one.
A) (0.274, 0.536) a 99% confidence interval of π and we
conclude it is a fair coin.
B) (0.293, 0.547) a 99% confidence interval of π and we
conclude it is a fair coin.
C) (0.304, 0.496) a 99% confidence interval of π and we
conclude it is a fair coin.
D) (0.324, 0.486) a 99% confidence interval of π and we
conclude it is a fair coin.
E) (0.433, 0.509) a 99% confidence interval of π and we
conclude it is a fair coin.
F) (0.274, 0.536) a 99% confidence interval of π and we
conclude it is not a fair coin.
G) (0.293, 0.547) a 99% confidence interval of π and we
conclude it is not a fair coin.
H) (0.304, 0.496) a 99% confidence interval of π and we
conclude it is not a fair coin.
I) (0.324, 0.486) a 99% confidence interval of π and we
conclude it is not a fair coin.
J) (0.433, 0.509) a 99% confidence interval of π and we
conclude it is not a fair coin.
