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.

a) \( \frac{x^{3}-5 x+1}{x-2} \)

7. Show how the Distributive Property can make the arithmetic simpler in the following problems \( \begin{array}{ll}\text { a. } 3 \cdot(50.15) & \text { b. } 5(108)\end{array} \)

32 What is the simplest form of \( \frac{2 a-(a+b)}{a^{2}-b^{2}} \) ? \( \begin{array}{ll}\text { A } a+b & \text { B } a-b \\ \text { C } \frac{1}{a+b} & \text { D } \frac{1}{a-b}\end{array} \)
