The American Community Survey estimates that 47.1% of women ages 15 and over are married. Assume this number is accurate due to the large size of the survey. We take a simple random sample of 85 women in this age range. (a) Are we more likely to select exactly 40 married women or exactly 50 married women? Clearly explain your reasoning. [There are multiple possible good explanations with varying levels of necessary calculation.] (b) What is the probability we select 45 or more married women? Find an exact value using the appropriate StatCrunch function. Remember to paste the entire output. (c) What is the probability of selecting 45 or more married women? This time approximate the probability using a normal distribution
