a. What is the value of our sample statistic?b. What is the critical value for this level of confidence? c. What is the standard error of our sample statistic?d. What is the margin of error for this level of confidence?e. The 95% confidence interval for the true proportion of adult residents who have smartphones is between _____ and ______ The Scenario: Suppose that a market research firm is hired to estimate thepercent of adults living in a large city who have smart phones. Four hundredrandomly selected adult residents in this city are surveyed to determinewhether they have cell phones. Of the 400 people sampled, 336 responded yes- they own smart phones.In this problem, we will calculate and interpret a confidence interval estimatefor the true proportion of adult residents of this city who have smart phones.We would like to find a 95% confidence interval for the the true proportion ofadult residents of this city who have smart phones. Answer each of thefollowing questions, being careful to round to the appropriate number ofdecimal places.
