82. The Vegetarian Resource Group commissioned Harris Poll in 2016 to conduct a nationally repre- sentative online poll of 2,015 American adults aged 18 and above. They found that \( 3.3 \% \) of the respondents identified as vegetarian. Food habits in India tend to have a large religious and social component. How does the popularity of the vegetarian diet differ in the United States and India? A 2014 survey conducted by the Registrar General of India found that \( 29 \% \) of Indians were vegetarian. Suppose the proportion was obtained from a random sample of 1,000 Indians. (a) Construct and interpret a \( 99 \% \) confidence interval for the difference in proportions of vege- tarians in India and the United States. (b) Based on the interval, what kind of evidence do you expect to have for the alternative in a two-sided hypothesis test? Explain.
