2. A random sample of 1500 students was selected from among the senior high school studentsacross the Philippines. The average number of hours per day a typical student spends takingmeals was found to be 2 h. Suppose the standard deviation of the population is s =: 0.5 h.a. Construct the appropriate confidence intervals for the true mean number of hours per day atypical student spends taking meals. Summarize your answers in the table below.Level of Confidence(1 – a) * 100% Confidence Interval for u(1 — а) * 100%Lower LimitUpper Limit90%95%98%99%b. Compare the confidence intervals obtained here with those in item 1. Discuss the effect ofthe sample size on the length of the confidence intervals for the same level of confidence andthe same population standard deviation. That is, what happens to the length of the confidenceintervals when the sample size is increased?

A statistician wants to determine if there is a significant difference in the average height of male and female college students. He collects a random sample of 100 males and 100 females and calculates their heights (in cm). The sample mean height for males is 175 cm and the sample mean height for females is 165 cm.
