Suppose that 44% of all adults think that airline travel is safer than driving. An opinion poll plans to ask a simple random sample (SR5) of 1021 adults about airplane safety. The proportion of the sample who think that airline travel is safer than driving will var)r if we take many samples from the same population. The sampling distribution of the sample proportion is approximately Normal with mean of 0.44 and standard deviations about 0.016. Sketch this Normal curve and use it to answer the following questions. What is the probability p that the poll gets a sample in which more than 40.3% of the people think that airline travel is safer than driving? Report your answer as a percent
