Suppose you have no idea how the amount of time required to perfectly cook a pancake is distributed, so you measure the cooking time for a sample of 129 random pancakes (cooked under identical conditions) and find that the average cooking time for this sample was 85 seconds, and the sample standard deviation of the cooking times for this group of 129 pancakes was 17 seconds. Your friend believes that the true average cooking time for pancakes is 101 seconds and wants you to use your new stats skills (and this pancake data) to test the null-hypothesis that the true mean is 101 seconds, given your observed sample mean of 85 seconds. What is the absolute value of the t-stat is associated with this hypothesis test? (Enter only a positive number) (Note: Your sample size, mean cooking time, and sample standard deviation may vary across these questions)
