Help Answer Below label) each Hypothesis test for a proportion ("top" variable) State the assumptions for this test. Alpha-.05 Part 2 In part 2, you will calculate hypothesis test for a mean and proportion by hand using the SPSS output provided. Population Data You receive data on the box office earnings of the 300 top-earning movies since 1977. You have two variables. The first variable, "earnings" is the total earnings of the movie (in millions). The second variable, called "top", is a binary variable with "1" indicating that the movie made at least $300 million. Here are the descriptive results for "earnings": State the null and alternate hypotheses. Calculate the test statistic based on your sample. N Mean Earnings 300 387.199 Valid N (listwise) 300 Here are the descriptive results for "top":" N Mean 12 Top Valid N (listwise) 300 300 .66 use for last question What is the p-value? What is the critical value (from the r table)? .State your decision about the null, how you know it, and your best estimate for the population value. Sample Data You randomly selected 25 cases from the population and found the following: use for all Earnings Top Valid N (listwise) Descriptive Statistics N 222 Mean 352.600 .52 Std. Deviation 125.6915 .510 except last. Calculate the confidence interval for the proportion. Does the population proportion fall within this range?
