Problem Solving Write all the steps for the statistical testing. The homogeneity of the chloride level in a water sample from a lake was tested by analyzing portions drawn from the top and from the bottom of the lake, with the following results in ppm Ci: Top 26.30 26.43 Bottom 26.22 26.32 26.28 26.19 26.49 26.20 26.11 26.42 Determine if there is a significant difference (at 95% confidence level) between the chloride level in the top and bottom levels of the lake.
