1.  A study of parallel interchange ramps in the Orlando reveals that many drivers don't employ the overall length of parallel lanes for acceleration, but seek as soon as possible an proper gap in the major stream of traffic for merging. At the parallel lane of Lake Mary Boulevard and Interstate 4, the probability that the driver uses less than half the lane length before merging is 0.54 (or 54%). Assume we want to monitor the merging patterns of the random sample of 330 drivers at the parallel lane of Lake Mary Boulevard and Interstate 4. What is the estimate probability that 200 of those drivers or less will employ less than half the parallel lane length before merging?

2.  The FDA conducted the study to measure the effectiveness of drug it recently developed to minimize the level of Total Blood Cholesterol.
