About two-thirds of companies in America test newly-hired employees for drugs, and 3.8% of those prospective employees test positive (based on data from the American Management Association). The Sigma Electronics Company tests 150 prospective employees. If the 3.8% is assumed to be accurate, find the probability that 20 or more (out of 300) will test positive. What is the chance that less than ten will test positive ? Use the normal approximation to the binomial.

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
