Let X equal the number of female children in a three-child family. Among students who were taking statistics, 52 came from families with three children. For these families x = 0, 1, 2, and 3 for 5, 17, 24, and 6 families, respectively.

(a) Conduct a Chi-square goodness-of-fit test to test the null hypothesis that the distribution of X is B(3, 0.5) at 0.05 significance level.

(b) Conduct a Chi-square goodness-of-fit test to test the null hypothesis that the distribution of X is B(3, p) at 0.05 significance level. Estimate p.

9.1-5. Let X equal the number of female children in a three-child family. We shall use a chi-square goodness-of- fit statistic to test the null hypothesis that the distribution of X is b (3, 0.5). (a) Define the test statistic and critical region, using an α = 0.05 significance level. (b) Among students who were taking statistics, 52 came from families with three children. For these families, x= 0, 1, 2, and 3 for 5, 17, 24, and 6 families,...

Three fair coins are flipped independently. Let X be the number of heads among the three coins. (1) Write down all possible values that X can take. (2) Construct the probability mass function of X. (3) What is the probability that we observe two or more heads. (i.e., P(X ≥ 2)) (4) Compute E[X] and Var(X).

Let X be the number of students who attend counseling at a certain time of day. Suppose that the probability mass function is as follows p (0) = .15, p (1) = .20, p (2) = .30, p (3) = .25, and p (4) = .10. Determine: a) Is this a valid probability mass function? Why? b) Obtain the cumulative probability function c) What is the probability that at least two students come to counseling d) What is the probability...
