1. Estimate the interval for the population proportion from each of the following. Then

interpret the result.

a. X = 500 , n = 812, 95% confidence

b. X = 842 , n = 1200, 95% confidence

c. X = 523 , n = 972, 99% confidence

2. In a survey, 1000 Grade 8 students were asked if they read story books. There were

318 who said yes. What proportion of the students does not read story books? Use

95% confidence interval to determine the population proportion p of all Grade 8 who

read storybooks. Does the data suggest positive attitude toward reading?​
