Life on Other Planets Forty-five percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 110 randomly selected individuals and found 66 believed that there is life on other planets. At α = 0.05, is there sufficient evidence to conclude that the percentage differs from 45%? Use the critical value method with tables. Do not round intermediate steps. (a) State the hypotheses and identify the claim. (b)Find the critical value(s) (c) Compute the test value. (d) Make the decision. (e) Summarize the results.
