Question 9 use the calculator provided to solve the following problems. suppose that χ2 follows a chi-square distribution with 18 degrees of freedom. compute p≤χ226. round your answer to at least three decimal places. suppose again that χ2 follows a chi-square distribution with 18 degrees of freedom. find k such that =p> χ2k0.1. round your answer to at least two decimal places. find the median of the chi-square distribution with 18 degrees of freedom. round your answer to at least two decimal places.

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
