The superintendent of a unified school district of a small town wants to make sure that no more than 5% of the students skip more than 10 days of school in a year. A random sample of 145 students from a population of 800 showed that 12 students skipped more than 10 days of school last year. What is the upper bound or limit of the 95% confidence interval for the proportion of students who skipped more than 10 days of school last year
Upper bound will be given as
Sample Proportion (p) + 1.645*Sqrt(p*(1-p)/n)
= 12/145 + ...
