One Sample Proportion Inference Problem: Conduct a Hypothesis Test: Be sure to write all responses in context of the problem. In 2020, a random sample of 200 U.S. adults were surveyed concerning their belief in UFOs (Unidentified Flying Objects). 35 adults stated they had seen a UFO. In 1996 a Gallup poll stated that 12% of adults in the U.S. have reported seeing a UFO. Do the data from the 2020 survey indicate that in 2020, the proportion of U.S. adults who have seen a UFO is higher than the 12% stated in 1996? Use a significance level of a=0.05 Hypothesis: Let p represent the true proportion of U.S. adults in 2020 who have seen a UFO. Write the null and alternative hypotheses (2 points) Model: State the Model and check the conditions: (4 points) Independence: 10% Condition: Success/Failure:Mechanics: Find the test statistic, draw a picture indicating the p-value and find the p-value (3 points) Conclusion: Write a conclusion in the context of the problem.
