percentage below. a. What is the approximate percentage of women
with platelet counts within 2 standard deviations of the mean, or
between 120.1 and 392.9? b. What is the approximate percentage of
women with platelet counts between 51.9 and 461.1?
The blood platelet counts...
The Empirical Rule states that for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean. The heights of women at a large university are approximately bell-shaped, with a mean of 64 inches and standard deviation of 3 inches. Use this information to answer the questions. (a) What is the probability that a randomly selected woman from this university is 67 inches or taller? (Give the answer to two decimal places.) (b) What is the...
