A random survey of 75 death row inmates revealed that the average length of time on death row is 17.7 years with a standard deviation of 6.2 years. Conduct a hypothesis to test the state of CT's claim. What type of test should be run? t-test of a mean Oz-test of a proportion The alternative hypothesis indicates a two-tailed test O right-tailed test O left-tailed test Calculate the p-value.

- Suppose a small company that manufactures cereal bars own two scales that weigh their products (say A and B). Quality control manager in this company is concerned that scale A is erroneous. He takes a sample of 20 cereal bars and weigh each of them using both scales A and B. Assume that you were given a spread sheet that include weights of the 20 cereal bars reported by two scales. Explain how you would approach testing the QC managers’ concern. What type of tests/CI you would construct to help him make a decision?

- The 2007-2008 financial crisis has been considered the worst financial crisis since the Great Depression of the 1930s. It resulted in the collapses of several large financial institutions and led to great concerns about the stability of global financial systems. Since then, investors’ views regarding the growth of economy have been diverging significantly. Many efforts have been made by the government to ensure investors’ confidence in the economy. The table below summarizes a recent survey on investors’ views of the economy. Investors are categorized according to the size of their assets. (a) What is the probability that an investor with more than 1 billion dollars asset believes that the economy is getting worse? (b) What is the probability that an investor who believes the economy is getting better has assets with value more than 100 million dollars?
