Pie Pizzeria hires you on as a statistical consultant. They want you to analyze their new promotion where the pizza is free if it takes more than 30 minutes for delivery. They request all analyses use 95\% confidence levels. Since your previous margin of error was too high, you gather a larger sample of 20 delivery times. In Excel you calculate the mean to be 25.5 minutes, and the sample standard deviation to be 3.7 minutes. You see that the sample standard deviation is even larger now! Will the margin of error be larger now? There is not enough information to determine the answer No, because the larger sample size also lowers the margin of error Yes, because a larger standard deviation from the new sample will make the new margin of error larger Yes, because the larger sample size also increases the t-value
