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 20 of these beverages for the quality assurance team, which finds a sample mean of 44.09 with a standard deviation of 2.62 degrees Celsius. Calculate the margin of error required for a 90% confidence interval for the population mean. Round your answer to 2 decimal places. Recall Canvas truncates trailing Os automatically 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).
