PETA #8 DIRECTION: Read, analyze, and answer the following problems below regarding length of the confidence interval, margin of error, and range of values or what we called confidence interval. Show your complete solutions and write it on a clean sheet of paper/s. No solution, automatically wrong. 1. Given the following data below, compute for the Upper Limit, Lower Limit, Margin of Error, and length of the confidence of interval. o = 47, Confidence Level = 95%, x = 85, and n = 44 2. Compute the length of the confidence interval with a sample size of 240 and with a population standard deviation 60 having an 80% confidence level. 3. You are planning to buy a cellphone with a good quality in order to attend the online class. The average price of 50 cellphones is Php13,500 with a margin of error of Php 273.65 and a confidence level of 99%. What is the confidence interval?
