Forty-two percent of people believe that there is life on other planets. A scientist does not agree with this finding. He surveyed 110 randomly selected individuals and found 44 believed that there is life on other planets. At (alpha) = 0.05, is there sufficient evidence to conclude that the percentage differs from 42%? Use the critical value method and tables. A. State the hypotheses and identify the claim with the correct hypothesis. B. Find the critical value(s). C. Compute the test value. D. Make the decision. E. Summarize the results.
