Question details

5. (20 points) It is common to believe that the median of the heart beat rate of 16 years old boys is 75. To determine if there has been any change in this value, a random sample of 100 boys has been selected. If 60 boys have heart beat rate above 75, test the hypothesis that the median is equal to 75 at level 5%, (Use Normal approximation for Binomial distribution to calculate the p-value) END
