An analysis of city drinking water for total hardness was done by two students in the laboratory and produced the following results (in ppm CaCO3):
Student A: 228.3, 226.4, 226.9, 227.1, and 228.6.
Student B: 229.5, 226.1, 230.7, 223.8, and 227.5What is the 95% confidence interval for the mean?
2. As the director of a research laboratory you are paid to decide if there is a significant
difference between the mean values of two sets of data obtained by two different scientists, a
senior scientist and one recently hired. Use 95% CL. (t at df = 10 is 2.23)
Data of Senior Scientist: Xmean = 24.66% with s = 0.06% for n = 5
Data of the New Kid: xmean = 24.55% with s = 0.10% for n = 7
