The October 2019 Gallup Poll reported the proportion of Republicans, Independents, and Democrats who favor the legalization of marijuana. Here are the results: Step 1: Test Set-Up Step 2. Select the Level of Significance, α A 5 percent significance level is selected. Step 3. State the Null Hypothesis (H0) and Alternate Hypothesis (H1) H0: H1: Step 4. Compose the Decision Rule Step 5. Calculate the Value of the Test Statistic, p-value, and estimate statistical power (Use G*Power) Use G*Power to calculate statistical power. Use these settings: Test family: z tests Statistical test: Proportion: Difference between two independent proportions Type of power analysis: Post hoc: Compute achieved power – given α, sample size and effect size Step 6. Decide and Report
1. English test was administered to 19 boys and 21 girls, Test whether the girls differ in their scores from that of the boys. Use a=0.05. Follow the steps in hypothesis testing. Вoys: 30, 28, 25, 24, 16, 10, 19, 27, 28,16, 15, 23, 20, 18, 17, 12, 28, 9, 15. Girls: 27,18, 15, 10, 25, 29, 19, 23, 26, 20, 18, 10, 16, 28, 29, 24, 20, 24, 27, 12, 9.
For each prompt below, do the following: i.) State the Null / Alternate Hypothesis ii.) Determine the Critical Value iii.) Determine Sample Score + Plot (t or z) iv.) Make a Conclusion 3.) According to Nielsen Media, of the US homes that owned at least one TV, 83% had two or more. A local cable company canvassing a town to promote a new cable service found that of the 300 houses visited, 240 of them at two plus TVs. At ? = 0.10 is there sufficient evidence to conclude that the proportion is less than the one in the report?
please show all steps USING EXCEL ONLY FORMULAS a) Identify the null and alternative hypotheses for this test b) Identify the test statistic for this hypothesis test. c) Identify the P-value for this hypothesis test. d) Identify the conclusion for this hypothesis test.
18. A credit card company claims that the mean time the customers spend on hold is 3.5 minutes. An employee of this company believes that customers spend more than 3.5 minutes on hold. A random sample of n = 36 calls is selected and the mean time the customers in this sample spent on hold was 5.15 minutes. All conditions for inference were met and the p-value for the appropriate hypothesis test was 0.031. Which of the following statements is the best interpretation of the p-value? (A) There is a 0.031 probability that the alternative hypothesis is true. (B) There is a 0.031 probability that the null hypothesis is true. (C) If the null hypothesis is true, there is a 0.031 probability of finding convincing evidence that 5.15 minutes is greater than 3.5 minutes. (D) If the null hypothesis is true, the probability of finding convincing evidence that the null hypothesis is true is 0.031. (E) If the null hypothesis is true, the probability of observing a sample mean of at least 5.15 minutes…
