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

Answer 1

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.
