Homework Assignment
AI Summary
This assignment focuses on applying statistical techniques to analyze data related to zinc concentration in drinking water. The solution begins by differentiating between primary and secondary data, highlighting the methods of collection for each. It then introduces various statistical techniques, including frequency distribution, mean, standard deviation, and hypothesis testing. A case study on zinc concentration in bottom and surface water is presented, detailing the data collected from ten locations. The solution calculates frequency distributions, mean, and standard deviation using Excel. Furthermore, it performs a paired t-test to determine if the true average concentration in bottom water exceeds that of surface water. The hypothesis, significance level, critical value, test statistic, and conclusion are explicitly outlined, demonstrating the application of statistical methods to draw meaningful inferences from the data.
