A study is to be done to compare math achievement in the two different middle schools in a certain city. A random sample of middle school students at North Middle School is chosen and their math achievement scores recorded. A random sample of middle school students at South Middle School is chosen their scores recorded. The data is provided below. Assume that the data meets the conditions to calculate a confidence interval. North: 45 50 60 63 52 57 51 44 55 57 South: 48 62 73 70 58 64 58 42 69 62 1. Are these considered dependent or independent populations? 2. What is the point estimate of the difference in the mean math achievement scores of students at North and South Middle Schools? 3. We are 95% confident that the difference in the mean math achievement scores at North and South Middle school is between and . 4. Because the interval we .
