A geologist collected 20 different ore samples of equal weight and randomly divided them into two groups. She measured the titanium (TI) content of the samples using two different methods. Method 1 Method 2 0.012 0.012 0.013 0.016 0.014 0.011 0.016 0.014 0.013 0.014 0.013 0.011 0.013 0.012 0.012 0.011 0.016 0.013 0.014 0.015 (a) Draw stem and leaf plots for the two data sets. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.) Stem and Leaf Plot for Method 1 stem leaf 10 11 12 13 14 15 16 Stem and Leaf Plot for Method 2 stem leaf 10 11 12 14 15 16 Visually compare their centers and their ranges. The standard deviation and mean of Method 1 appears to be smaller than the standard deviation and mean of Method 2. The standard deviation and mean of Method 1 appears to be larger than the standard deviation and mean of Method 2. The standard deviations and mean of Methods 1 and 2 are equal. (b) Calculate the sample means and standard deviations for the two sets. (Round your standard deviations to five decimal places.)
