Question

Shortly after the major oil spill in the Gulf of Mexico that occurred in April 2010 due to an explosion on an oil rig, a Rasmussan Poll found that 23% of respondents were against offshore drilling for oil. In an effort to confirm these results, an environmental group randomly selected 200 adults and asked them their opinions about offshore drilling.
a. What is the probability that 40 or more people from this sample are against offshore drilling for oil?
b. What is the probability that 50 or more people from the sample are against offshore drilling for oil?
c. If 62 people in the sample indicated that they are against offshore drilling for oil, what conclusions can the environmental group make?
