Step 1. You need 4 numbers: Old method's average: m = 0.0126 New method's average: X-bar (you need to calculate it from the data below) Standard deviation of sample data 's' (you need to calculate it from the data below) n number of samples 'n' (you need to count them yourself from the data below) Step 2. State the null and alternate hypothesis. Step 3. Calculate the T test statistic from the formula found in the t test lecture and in your online textbook. Step 4. Determine the critical T value [Hint: (n - 1) is 25 - 1 = 24 df] and considering a 95% confidence.
