In 1945, an organization asked 1421 randomly sampled American citizens, "Do you think we can develop a way to protect ourselves from atomic bombs in case others tried to use them against us?" with 744 responding yes. Did a majority of the citizens feel the country could develop a way to protect itself from atomic bombs in 1945? Use the a = 0.05 level of significance.

According to a study, the proportion of people who are satisfied with the way things are going in their lives is 0.86. Suppose that a random sample of 100 people is obtained. Complete parts (a) through (e) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). O A. The response is qualitative because the number of people satisfied can be counted. O B. The response is quantitative because the number of people satisfied can be counted. O C. The response is quantitative because the responses can be classified based on the characteristic of being satisfied or not. YD. The response is qualitative because the responses can be classified based on the characteristic of being satisfied or not. (b) Explain why the sample proportion, p, is a random variable. What is the source of the variability? The sample proportion p is a random variable because the value of p represents a random person included in the…
