Solutions

Expert Solution

TOPIC:Test for the population proportion.

[ z0.025 = 1.96 , from z table critical values.]

CONCLUSION:

There is not sufficient evidence to conclude that the coin is unfair, at 5% level of significance.

Q7 A fair coin is tossed three times independently: let X denote the number of heads on the first toss (i.e., X = 1 if the first toss is a head; otherwise X = 0) and Y denote the total number of heads. Hint: first figure out the possible values of X and Y , then complete the table cell by cell. Marginalize the joint probability mass function of X and Y in the previous qusetion to get marginal PMF’s.
