1 Researchers claim that the mean body temperture of healthy

1) Researchers claim that the mean body temperture of healthy adults is different from 98.6 F. In order to test this claim researchers collected sample data from 100 individuals. The mean body temperature of those individuals is 98.2 F and the standard deviation is 0.68 F.

(a) Set up the nulland alternative hypothesis to the test researchers claim that the mean body temperature of healthy adults is different from 98.6 F at 95% level of confidence. Is it a one-tailed or two tailed hypothesis?

(b) Determine the critical ( rejection ) region(s).

(c) Compute the test statistics and determine whether we should reject theresearchers\' claim.

(d) Find the corresponding p-value and test the claim that mean body temperature is different from 98.6 F.

(e) Another resercher claims that the mean body temperature is greater than 98.6 F. Test the researcher\'s claim at 95% level of confidence.
