A confidence interval was constructed to estimate the difference of proportions from two populations. The interval was found to be (-0.42, 1.87). Based on this interval, it is reasonable to conclude that there is NO difference between these two population proportions.  

An academic counselor examined data from 84 students from the Fall semester and 106 students from the Spring semester. She found that 74% of the Fall students booked appointments on time, whereas 62% of the Spring students did. Construct a 95% confidence interval to investigate the difference of proportions between the two semesters. (Treat Fall as Group1 and Spring as Group 2.)

An HR director conducted an additional survey for the two office locations. A confidence interval was constructed for the true difference between lunch prices at these two locations and found to be (2.415, 3.3847).  The center city employees argue that only they should receive the raise. What does your confidence interval say about that? Center City Suburban

Questions 11 and 12 refer to the same scenario: A scientist wants to predict the impact of minutes drying time (x) on the strength of a cement sample (y).  A regression line was computed to model the dataset shown below, resulting in the linear equation 

A confidence interval is constructed based on the [part1] statistic. The purpose of the confidence interval is to estimate the true value of the [part2] parameter.
