(b) Does the confidence interval constructed in part (a) contain the value 98.6°, the usual average temperature cited by physicians and others? If not, what conclusions can you draw?
O Since the set of possible values for u given in the confidence interval does not include the value μ = 98.6°, it is not likely that the true average body temperature for healthy humans is 98.6°, the usual average temperature cited by physicians and others.
O Since the set of possible values for μgiven in the confidence interval includes the value μ = 98.6°, it is plausible that the true average body temperature for healthy humans is 98.6°, the usual average temperature cited by physicians and others.
