In each of Exercises, we have given the P-value for a hypothesis test. For each exercise, refer to Table to determine the strength of the evidence against the null hypothesis. P-value Evidence against H0 P > 0.10 Weak or none 0.05 < P ≤ 0.10 Moderate 0.01 < P ≤ 0.05 Strong P ≤ 0.01 Very strong P = 0.184

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.           (b)Find the critical value(s). Round the answer to two decimal places. If there is more than one critical value, separate them with commas. Critical Value(s): (c)Compute the test value. Round the answer to at least two decimal places. z= (d)Make the decision.   (choose one) the null hypothesis   (e)Summarize the results.   There is ▼(Choose one) that the percentage of people who believe that there is life on other planets differs from  43% .

Solve the problem. A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are Ho: p = 0.6 and Ha: P < 0.6. The test statistic and p-value for the test are z = -1.51 and p-value = 0.0655. For a significance level of a = 0.05, choose the correct conclusion regarding the null hypothesis. O None of these. O There is sufficient evidence to warrant rejection of the null hypothesis. There is insufficient evidence to warrant rejection of the null hypothesis.
