A bakery is analyzing whether cookie diameter varies with baking temperature. An experiment was run, with (20) cookies baked at a “low” temperature and (20) cookies baked at a “high” temperature. Assume the variance in height is equal for both temperatures. Which statistical test should be used to determine whether the mean cookie height from the “low” temperature is the same as the mean cookie height from the “high” temperature?
