Question 1015571:
Suppose that in a certain population the true mean clotting time of blood from individuals with no clotting deficiency is 180, and the standard deviation of the distribution of individual clotting time of blood is 50. The distribution is considered to be normal.
a) What propotion of the population has clotting time of blood between 129 and 230?
b) What percentage of the population has clotting time of blood in the range 180± 50
c) b) What percentage of the population has clotting time of blood in the range 180± 100
d) b) What percentage of the population has clotting time of blood in the range 180± 150
e) What is the 95% percentile?
