The folks at the organization want to know if this represents sufficient evidence to conclude a majority (more than 50%) of high school seniors in the country believe they will not have enough money in college. (a) What does it mean to make a Type II error for this test? (b) If the researcher decides to test this hypothesis at the α=0.05 level ofsignificance, compute the probability of making a Type II error, β, if the true population proportion is 0.54. What is the power of the test? (c) Redo part (b) if the true population proportion is 0.580.58.
