Determine the standard error of the mean for the following situation. Use the formula for SEM, where s represents the standard deviation and n in the sample size. Round answers to the nearest hundredth. An analysis of 41 items on the café’s menu found that the menu items had an average of 450 calories, with a standard deviation of 23 calories. Round your answer to the nearest hundredth.
