The temperature-controlled environment in a hospital intensive care unit is monitored by an intelligent nstrument that measures temperature every minute and calculates the mean and standard deviation of he measurements. If the mean is 50°C and the standard deviation (o) is 2.15, (a) What percentage of the time is the temperature less than 45°C? (b) What percentage of the time is the temperature between 47°C and 53°C? (c) Determine the value of a such that 90% of measurements lie within the boundaries of txo.
