Question

Question 1: Sociologists randomly surveyed 120 families living in Nashville and found that 38 families eat at least three meals per week together as a family. A random sample of 90 families living in Seattle found that 25 families eat at least three meals per week together as a family. a. Check the conditions of the Central Limit Theorem. b. Find a 95% confidence interval for the difference in the proportions of families in Nashville vs Seattle that eat at least three meals per week together as a family. \begin{itemize} \item State the calculator function and list any inputs used. \item Round to 3 decimal places. \item For 1 extra credit point, include a labeled sketch of the sampling distribution. \end{itemize} c. Is the interval positive, negative, or does it include 0? Does this indicate a significant difference? d. Interpret the confidence interval in a complete sentence.
