Fair Coin? A coin is called fair if it lands on heads 50% of all possible tosses. You flip a game token 100 times and it comes up heads 60 times. You suspect this token may not be fair.

(a) What is the point estimate for the proportion of heads in all flips of this token? Round your answer to 2 decimal places.

(b) Construct the 99% confidence interval for the proportion of heads in all tosses of this token. Round your answers to 3 decimal places.

(c) Are you 99% confident that this token is not fair?
- No, because 0.50 is within the confidence interval limits.
-Yes, because 0.50 is not within the confidence interval limits.
-Yes, because 0.50 is within the confidence interval limits.
-No, because 0.50 is not within the confidence interval limits.

Fair Coin? In a series of 100 tosses of a token, the proportion of heads was found to be 0.39. However, the margin of error for the estimate on the proportion of heads in all tosses was too big. Suppose you want an estimate that is in error by no more than 0.04 at the 90% confidence level. (a) What is the minimum number of tosses required to obtain this type of accuracy? Use the prior sample proportion in your...

You flip a fair coin. If the coin lands heads, you roll a fair six-sided die 100 times. If the coin lands tails, you roll the die 101 times. Let X be 1 if the coin lands heads and 0 if the coin lands tails. Let Y be the total number of times that you roll a 6. Find P (X=1|Y =15) /P (X=0|Y =15) .

Suppose you flip a fair coin until it lands heads up for the first time. It can be shown (do not try to calculate this) that the expected value of the number of flips required is 2. Explain (with a sentence or two) what this expected value means in this context.

Consider a coin. Suppose you want to learn about the distribution of flips of the coin that land on Heads but you only want to flip the coin 20 times. Suppose you flip a coin 20 times and record the count and proportion of times it lands on Heads. Is the proportion of Heads among the 20 flips of the coin a parameter or a statistic? What symbol is used to denote the proportion?     Is the proportion of Heads among...

The theoretical probability of a coin landing heads up is 1/2 Does this probability mean that if a coin is flipped two​ times, one flip will land heads​ up? If​ not, what does it​ mean? Choose the correct answer below. A. ​Yes, it means that if a coin was flipped two​ times, at least one of the tosses would land heads up. B. ​Yes, it means that if a coin was flipped two​ times, exactly one of the tosses would...

You are flipping a fair coin with one side heads, and the other tails. You flip it 30 times. a) What probability distribution would the above most closely resemble? b) If 8 out of 30 flips were heads, what is the probability of the next flip coming up heads? c) What is the probability that out of 30 flips, not more than 15 come up heads? d) What is the probability that at least 15 out 30 flips are heads?...

Suppose you toss a coin 100 times. Should you expect to get exactly 50 heads? Why or why not? A. Yes, because the number of tosses is even, so if the coin is fair, half of the results should be heads. B. No, because the chance of heads or tails is the same, the chance of any number of heads is the same. C. No, there will be small deviations by chance, but if the coin is fair, the result...
