In a large city, 55% of people pass thedrivers' road test. Suppose that every day, 400 people independently take the test. Complete parts (a) through (d) below. a. What is the number of people who are expected to pass? The expected number is 220. (Round to the nearest whole number asneeded.) b. What is the standard deviation for the number expected to pass? The standard deviation is 10. (Round to the nearest whole number as needed.) c. After a great many days, according to the Empirical Rule, on about 95% of these days, the number of people passing will be as low as and as high as . (Hint: Find two standard deviations below and two standard deviations above the mean.) After a great many days, according to the Empirical Rule, on about 95% of these days, the number of people passing will be as low as and as high as .(Round to the nearest whole number as needed
