The standard hemoglobin reading for healthy adult men is 15g/100ml with a standard deviation of 2g. For a group of 25 men we find a mean hemoglobin of 16.0g. Obtain a 95% confidence interval and give its interpretation.© BrainMass Inc. brainmass.com June 3, 2020, 9:35 pm ad1c9bdddf
x-bar = 16, sigma = 2, n = 25
SE = sigma/sqrt(n) = 2/sqrt(25) = 0.4
The 95% CI for the mean is ...
