A large university is planning to build a new parking garage on campus that will be paid for by an increase in student parking fee. The student newspaper wanted to determine what proportion of the students favor the new garage. They selected a random sample of 180 students and found that 36 of them are in favor of the new garage. Calculate the upper limit of the 70% condence interval for the population proportion. Note: You may assume that the sample size is large enough for all required calculations
