Test the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats at the 0.02 significance level. the null and alternative hypothesis would be: h 0 : p m = p f h 1 : p m ≠ p f h 0 : p m = p f h 1 : p m < p f h 0 : μ m = μ f h 1 : μ m < μ f h 0 : p m = p f h 1 : p m > p f h 0 : μ m = μ f h 1 : μ m > μ f h 0 : μ m = μ f h 1 : μ m ≠ μ f the test is: left-tailed right-tailed two-tailed based on a sample of 20 men, 40% owned cats based on a sample of 20 women, 60% owned cats the test statistic is: (to 2 decimals) the p-value is: (to 2 decimals) based on this we: reject the null hypothesis fail to reject the null hypothesis

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

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
