The variance in a production process is an important measure of the quality of the process. A large variance often signals an opportunity for improvement in the process by finding ways toreduce the process variance. Jelly Belly Candy Company is testing two machines that use different technologies to fill three pound bags of jelly beans. The following tables contain a sample ofdata on the weights of bags (in pounds) filled by each machine.Machine 12.95 3.45 3.50 3.75 3.48 3.26 3.33 3.202Ha: 013.16 3.20 3.22 3.38 3.90 3.36 3.25 3.28State the null and alternative hypotheses.2Ho: 01 #3.20 3.22 2.98 3.45 3.70 3.34 3.18 3.353.12Conduct a statistical test to determine whether there is a significant difference between the variances in the bag weights for two machines.

Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy individuals are Normally distributed with a mean of 3.2 mg/dl. Some areas of the United States have naturally elevated arsenic levels in the ground and water supplies. Researchers took a sample 20 water samples from a particular area and measured the arsenic levels in each of the 20 water samples. They want to determine if there is sufficient evidence to conclude that the arsenic level in that area is higher than 3.2 mg/dl. hypothesis test for one population mean (unknown population standard deviation) confidence interval estimate for one population mean (unknown population standard deviation) hypothesis test for population mean from paired differences confidence interval estimate for population mean from paired differences hypothesis test for difference in population means from two independent samples confidence interval estimate for difference in population means from two…
