Since you have already tossed a normal coin 12 times, and got zero heads, what is the probability that you will have to toss at least 4 more times to get the first face?

Expert Solution

In simple word we have to toss atleat 4 times means we not get head in first 3 toss. And the probability of not getting head in first 3 trial = q^3 = 0.5^3 =0.125

A coin that lands on heads with a probability of p is tossed multiple times. Each toss is independent. X is the number of heads in the first m tosses and Y is the number of heads in the first n tosses. m and n are fixed integers where 0 < m < n. Find the joint distribution of X and Y.

Suppose that you tossed a coin 1000 times in which 560 of the tosses were heads while 440 were tails. Can we reasonably say that the coin is fair? Justify your answer. Hint: use the concept of p-values. To evaluate the resulting probability, use an approximation by way of the CLT. Why does this offer a good approximation? Use a z-table or R to evaluate the N(0,1) cdf.

3. A coin was tossed 10 times and “heads” appeared exactly 2 times. Is there sufficient evidence that the coin is not fair, that is that the proportion of heads is less than 0.5, at the α = 0.05 significance level? (Note: the sample size is small.) Do the5 step process to show work.
