QUESTION 8

  1. We wish to check that normal body temperature may be more than 98.6 degrees for a certain population. In a random sample of 18 individuals from this population, the sample mean was found to be 98.87 and the sample standard deviation was 0.482. Assume the population is normally distributed. Use a = 0.05.

    What are your null and alternative hypotheses?

       

    H0: µ < 98.6,   Ha: µ = 98.6

       

    H0: µ = 98.6,   Ha: µ > 98.87

       

    H0: µ = 98.87,   Ha: µ > 98.87

       

    H0: µ = 98.6,   Ha: µ > 98.6
