Test the claim that the mean body temperature is less than 98.6 using a=0.05. assume a sample of 16 yielded a mean of 98.2 with a standard deviation of 0.6
Use the same method as given in later post, but since you only have SD for sample, use that in the divisor.
Z = difference between means/√SE^2
I hope this helps. Thanks for asking.
