I\\I \\J A survey indicates that you should always try to negotiate for a better deal when shopping or paying for services. In fact, based on this survey, 40% of the people under the age of 34 were more likely to "haggle," compared to only 10% of those aged 65 and older. Suppose that this survey included 85 people under the age of 34 and 60 people who are 65 or older. IA use SA (a) What are the values off)under 34 and 1365 or older for the two groups in this survey? p under 34 I .4 1365 or over = C V (b) Find a 95% condence interval for the difference in the proportion of people who are more likely to "haggle" in the "under 34" versus "65 and older" age groups. (Round your answer to three decimal places.) to (c) What conclusions can you draw regarding the groups compared in part (b)? Since the value punder 34 p65 or older = 0 is not v V in the condence interval, it is Iikelythe two proportions are not the same v \\I . You should v 'I conclude that there is a difference in the proportion of people who were more likely to "haggle" between the two groups. Since the probable values of punder 34 p65 or older given by the interval contains only positive v q numbers, the proportion of people under 34 who "haggle" is likely greater than v J the proportion of people 65 or older who "haggle".
