The following test is proposed: To test the hypothesis that a particular coin is “fair” (equal probabilities of Heads and Tails), the coin is tossed 1000 times. The test will be that if the number of Heads in the 1000 tosses is between 475 and 525, then the statistician will conclude that the coin is “fair”. What is the probability that the statistician concludes that the coin is “fair” when in fact the P(Heads)=0.52 ?

To test the hypothesis that a coin is fair, you toss it 100 times. Your decision rules allow you to accept the hypothesis only if you get between 40 and 60 tails in 100 tosses. What is the probability of committing Type II error when the actual probability of tails is 0.7?

(a) A fair coin is tossed five times. Let E be the event that an odd number of tails occurs, and let F be the event that the first toss is tails. Are E and F independent? (b) A fair coin is tossed twice. Let E be the event that the first toss is heads, let F be the event that the second toss is tails, and let G be the event that the tosses result in exactly one heads...

A fair coin has been tossed four times. Let X be the number of heads minus the number of tails (out of four tosses). Find the probability mass function of X. Sketch the graph of the probability mass function and the distribution function, Find E[X] and Var(X).

A coin is tossed 10 times to test the hypothesis (?0) that the probability of heads is ½ versus the alternative that the probability is not ½. A test is defined by: reject ?0 if either 0 or 10 heads are observed. a. What is the significance level of the test? b. If in fact the probability of heads is 0.1, what is the power, (1 − ?), of the test?

Let p denote the probability that a particular coin will show heads when randomly tossed. It is not necessarily true that the coin is a “fair” coin wherein p=1/2. Find the a posteriori probability density function f(p|TN ) where TN is the observed number of heads n observed in N tosses of a coin. The a priori density is p~U[0.2,0.8], i.e., uniform over this interval. Make some plots of the a posteriori density.

A coin is tossed 5 times. Let the random variable ? be the difference between the number of heads and the number of tails in the 5 tosses of a coin. Assume ?[heads] = ?. Find the range of ?, i.e., ??. Let ? be the number of heads in the 5 tosses, what is the relationship between ? and ?, i.e., express ? as a function of ?? Find the pmf of ?. Find ?[?]. Find VAR[?].

Assume p represents the probability that a particular coin will show heads when randomly tossed. Don't assume its true that the coin is a “fair” coin wherein p=1/2. Determine the a posteriori probability density function f(p|TN) where TN is the observed number of heads n observed in N tosses of a coin. The a priori density is p~U[0.2,0.8], i.e., uniform over this interval. Create some plots of the a posteriori density.
