A coin is flipped 10,000 times and it is found that the relative frequency of heads is 0.51. How sure can you be that the coin is biased? Φ(1) − Φ(−1) = 0.68, Φ(2) − Φ(−2) = 0.95, Φ(3) − Φ(−3) = 0.997

A coin is flipped. 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 2 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?

I flipped a coin 49 times and got heads only 18 times. I feel like the coin is biased. I run a 1 sample z test proportion with the null hypothesis set to .5 (50%) to represent a fair coin. What's the p-value of the test? Would you reject the null hypothesis or fail to reject the null hypothesis?

question 3. A coin has two sides, Heads and Tails. When flipped it comes up Heads with an unknown probability p and Tails with probability q = 1−p. Let ˆp be the proportion of times it comes up Heads after n flips. Using Normal approximation, find n so that |p−pˆ| ≤ 0.01 with probability approximately 95% (regardless of the actual value of p). You may use the following facts: Φ(−2, 2) = 95% pq ≤ 1/4 for any p ∈...
