Life on Other Planets Forty-three percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 120 randomly selected individuals and found  69 believed that there is life on other planets. At α=0.01, is there sufficient evidence to conclude that the percentage differs from 43% ? Use the  P -value method with tables.   :H0   ▼(Choose one) :H1  ▼(Choose one) This hypothesis test is a ▼(Choose one) test.
