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, 30% 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 90 people under the age of 34 and 60 people who are 65 or older. (a) What are the values of Punder 34 and P65 or older for the two groups in this survey? under 34 P65 or over USE SALT = (b) Find a 95% confidence 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
