Expert Solution

a. "The mean body temperature for humans in fact is 98.6 degrees Farenheit but the result of the sampling lead to the conclusion that the mean body temprature for humans differ from 98.6 degrees Farenheit" is a Type I error. [Option(B)]

b. "The mean body temperature for humans in fact differs from 98.6 degrees Farenheit and the result of the sampling lead to that conclusion" is a correct decision. [Option(B)]

c. "The mean body temperature for humans in fact is 98.6 degrees Farenheit and the result of the sampling do not lead to the rejection of the fact that the mean body temprature is 98.6 degrees Farenheit" is a correct decision. [Option(A)]

d. "The mean body temperature for humans in fact differs from 98.6 degrees Farenheit but the result of the sampling fail to lead that conclusion" is a Type II error. [Option(C)]
