How does the popularity of the vegetarian diet differ in the US 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 vegetarians in India and the US. b. Based on the interval, what kind of evidence do you expect to have for the alternative in a two-sided hypothesis test? Explain.
