When a penny made before 1982, is tossed up into the air the probability of landing tails up is pretty close to 0.500 ( 50% chance); however, if the penny is set spinning on a flat smooth horizontal surface, it is more than 80% likely to land tails up. Explain.

What is the probability that a penny I have will land "heads" when tossed? To analyze this question I randomly toss the coin, n=3901 times. On x = 2500 of these tosses, the penny landed "heads." Based upon this sample, I wish to estimate p, the true probability of the penny landing "heads" when tossed. Let p̂ be the sample proportion of "heads" in our sample. Answer the following using R code. h) Assuming the same p̂ value =0.6409, what...

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 ∈...
