A polymer mixing process must be run until the blending is complete. Seven runs were done on a machine and the time to complete blending was recorded as (in hours): 17.9, 18.3, 14.1, 15.5, 16.4, 17.1, 18 Calculate the sample mean and standard deviation for this data. Your answers can be rounded to two decimal digit accuracy when entered.
