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.

a coin, assumed to be fair, is flipped thirty six times. Five heads are observed. An approximate 95 percent confidence interval for this number of heads can be constructed, to two decimal places, as: a(-1.09,11.09) b(0.00,10.88) c(0.07,9.95) d(-0.88,10.88) e(12.12,23.88)

If a heads is flipped, then the coin is flipped 4 more times and the number of heads flipped is noted; otherwise (i.e., a tails is flipped on the initial flip), then the coin is flipped 3 more times and the result of each flip (i.e., heads or tails) is noted successively. How many possible outcomes are in the sample space of this experiment?
