A random sample of n1 = 262 people who live in a city were selected and 117 identified as a "dog person." A random sample of n2 = 108 people who live in a rural area were selected and 55 identified as a "dog person." Find the 90% confidence interval for the difference in the proportion of people that live in a city who identify as a "dog person" and the proportion of people that live in a rural area who identify as a "dog person."

A study is made to determine if a rainy climate result in more students being absent from school during a semester than a warmer climate. Two groups of students are selected at random, one group from Bicol region and the other group from Mindanao. Of the 300 students from Bicol, 64 were absent at least 1 day during the semester, and of the 400 students from Mindanao, 51 were absent 1 or more days. Find the 95 % confidence interval for the difference between the fractions of the students who are absent in the two regions.
