An article contains measurements on samples of coal from several counties from Kentucky. In units of percent ash, five samples from Knott County had an average aluminum dioxide (AlO2) content of 32.17 and a standard deviation of 2.23. Six samples from Lesile County had an average AlO2 content of 26.48 and a standard deviation 2.02. A. Can we conclude that the variance of AlO2 content of coal sample differs between two countries? i. State hypothesis. ii. Compute P-value iii. What is your conclusion? B. Can you conclude that the mean of AlO2 contend of coal sample differs between two counties? i. State hypothesis. ii. Compute P-value iii. What is your conclusion?
