5. Suppose the mean number of days that all people who test positive for COVID-19 in the U.S. self-quarantine if they have no symptoms is 7.12 with a standard deviation of 1.08, and the mean number of days that all people who test positive self-quarantine if they have one or more symptoms is 12.67 with a standard deviation of 2.94. Calculate the standard error of a distribution of differences in sample means using sample sizes of n = 200.
