Coin Flips: If you flip a fair coin 5 times, what is the probability of each of the following? (please round all answers to 4 decimal places) a) getting all tails? b) getting all heads?
Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to flip the coin in order to obtain a 98% confidence interval of width of at most .19 for the probability of flipping a head? a) 150 b) 149 c) 117 d) 116 e) 152
If you flip a fair coin six times, what is the probability of having more heads than tails?
Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to flip the coin in order to obtain a 96.5% confidence interval of width of at most .12 for the probability of flipping a head? (note that the z-score was rounded to three decimal places in the calculation) a) 309 b) 226 c) 229 d) 312 e) 306 f) None of the above
