Math Problem Statement
A survey of 1 comma 0911,091 adults was asked, "Do you feel overloaded with too much information?" Suppose that the results indicated that of 542542 males, 238238 answered yes. Of 549549 females, 275275 answered yes. Construct a contingency table to evaluate the probabilities. Complete parts (a) through (d). Question content area bottom Part 1 a. What is the probability that a respondent chosen at random indicates that he/she feels overloaded with too much information? 0.4700.470 (Round to three decimal places as needed.) Part 2 b. What is the probability that a respondent chosen at random is a female and indicates that he/she feels overloaded with too much information? enter your response here (Round to three decimal places as needed.)
