After measuring the cortisol level in 30 students (see problem 1a) it is average cortisol levels measured at 324 nmol /I with a standard deviation of 48 nmol / I. We assume that the cortisol concentration follows a normal distribution. Rain out the margin of error in the measured average value for 95% confidence level. The standard normally distributed z-value is equal to 1.96 for a 95% confidence level.
