In a study of cell phone usage and brain hemispheric dominance, an Internet survey was emailed to 6987 subjects randomly selected from an online group involved with ears. There were 1308 surveys returned. Use a 0.01 significance level to test the claim that the return rate is less than 20%. Use the Pvalue method and use the normal distribution as an approximation to the binomial distribution. @ Identify the null hypothesis and alternative hypothesis. A. Ho: p0.2 '1:ij B. Ho: p > 0.2 H1:p=0.2 H1:p=0.2 ":ij C. H0: p = 0.2 {32- D. HO: p = 0.2 H1:p0.2 The test statistic is z = D. (Round to two decimal places as needed.) The P-value is D. (Round to three decimal places as needed.) Because the Pvalue is ':| the signicance level, |:| the null hypothesis. There is El evidence to support the claim that the return rate is less than 20%. A data set includes wait times (minutes) for the Tower of Terror ride at Walt Disney World's Hollywood Studios theme park at 5:00 PM. Using 36 of the times to test the claim that the mean of all such wait times is more than 30 minutes, the accompanying Excel display is obtained. Test the given claim by using the display provided from Excel. Use a 0.10 significance level. Click the icon to view the Excel display. . . . Identify the null and alternative hypotheses. Ho (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis. There sufficient evidence at the 0.10 significance level to the claim that the population mean of all wait times for the Tower of Terror ride at 5:00 PM is more than 30 minutes.Ho: H1: (Type inte Als.
