The difference in the Organic Chemistry final exam scores between last semester and three years ago will be analyzed by the dean. Although the standard deviations of these populations are unknown, the dean has evidence that they are equal. A sample of 41 of these scores from last semester had a mean of 63.7 and standard deviation of 4.6, and a sample of 37 scores from three years ago had a mean of 64.7 and standard deviation of 5. A claim is made that the mean final exam score from last semester ( 1) is less than the mean final exam score from three years ago (₂). For each part below, enter only a numeric value in the answer box. For example, do not type "z =" or "t=" before your answers. Round each of your answers to 3 places after the decimal point. (a) Calculate the value of the test statistic used in this test. Test statistic's value (b) Use your calculator to find the P-value of this test. P-value = 0.180 Submit Question
