A coffee chain with a franchise in Saskatoon is interested in piloting a new beverage. The chain wants to ensure that this beverage is served at a temperature of 40 degrees Celsius. Baristas create 19 of these beverages for the quality assurance team, which finds a sample mean of 37.95. They know the population standard deviation is 3.20 degrees Celsius. Calculate the margin of error required for a 98% confidence interval for the population mean. Round your answer to 2 decimal places. Recall Canvas automatically truncates trailing 0s without loss of marks (e.g., if you enter 1.00, Canvas changes this to 1, and you do not lose marks as a result).
