In a study of high-achieving high school graduates, the authors of a report surveyed 837 high school graduates who were considered "academic superstars" and 436 graduates who were considered "solid performers." One question on the survey asked the distance from their home to the college they attended. Assuming it is reasonable to regard these two samples as random samples of academic superstars and solid performers nationwide, use the accompanying data to determine if it is reasonable to conclude that the...

A study was conducted to determine if the students from the public universities take longer to graduate than the students from the private universities. 100 students from both the public universities and private universities were surveyed. Suppose that from the years of research, it was known that the population standard deviations were 1.58 years and 1 year respectively. The following data were collected. The public and private universities students took an average of 4.5 and 4.1 years respectively with a...

A study was conducted to determine if the salaries of elementary school teachers from two neighboring districts were equal. A sample of 15 teachers from each district was randomly selected. The mean from the first district was $28,900 with a standard deviation of $2300. The mean from the second district was $30,300 with a standard deviation of $2100. Assume the samples are random, independent, and come from populations that are normally distributed. Construct a 95% confidence interval for μ1 -...
