Drivers in a major city have been going to small towns in the region to take the drivers' road test, rather than taking the test in the city, because the pass rate in the small town 90%, which is much higher than the pass rate in the city. Suppose that every day, 300 people independently take the test in one of these small towns. Complete parts (a) thro (d). a. What is the number of people who are expected to pass? The expected number is. (Round to the nearest whole number as needed.) b. What is the standard deviation for the number expected to pass? The standard deviation is. (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 (Round to the nearest whole numbers as needed.) and as high as

Drivers in a major city have been going to small towns in the region to take the drivers' road test, rather than taking the test in the city, because the pass rate in the small towns is 90%, which is much higher than the pass rate in the city. Suppose that every day, 300 people independently take the test in one of these small towns. Complete parts (a) through (d). a. What is the number of people who are expected to pass? The expected number is. (Round to the nearest whole number as needed.) b. What is the standard deviation for the number expected to pass? The standard deviation is (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 (Round to the nearest whole numbers as needed.) d. If you found that one day, 274 out of 300 passed the test, would you consider this to be a very high number? because 274 is the Empirical Rule interval. and as high as
