### Hypothesis Testing for Mean HeightThe heights of young men are approximately normally distributed, with a mean of 69.7 inches. A random sample of heights from young men at a large university in the Midwest are listed below (in inches):74, 64, 71, 76, 67, 77, 68, 69, 73, 71, 71#### Research QuestionIs there sufficient evidence to say that the mean height for young men at the university is larger than the average?#### HypothesesState the appropriate null and alternative hypotheses.- \( H_0 \) (Null Hypothesis): \[ \mu \leq 69.7 \]- \( H_a \) (Alternative Hypothesis): \[ \mu > 69.7 \]#### ConclusionWhat is the correct conclusion for the hypothesis test?[Here you would typically conduct the hypothesis test by calculating the test statistic and comparing it to a critical value or calculating the p-value to reach a conclusion based on a given significance level, typically \(\alpha = 0.05\).]*Note: Fill in the squares and blank at the end with the appropriate values according to the results you obtain.*

O of 5 A random sample of 77 eighth grade students' scores on a national mathematics assessment test has a mean score of 273. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 270. Assume that the population standard deviation is 35. At a = 0.09, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). %3D (a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below. O A. Ho: μ2 270 (claim) Ha: В. Но: С. Но: u = 270 Ha: H = 270 (claim) Ha: H> 270 μ> 270 (claim) H 270 (claim) O E.

The P/E ratio is the stock price divided by the most recent 12 months of earnings. Suppose you are interested in seeing whether the current market is overvalued and would also like to know what proportion of companies pay dividends.

Percentage of 18- to 24-year olds living in parents' homes Refer to the figure at the right. At a = 0.05, can you support the claim that the proportion of men ages 18 to 24 living in parents' homes was greater in 1999 than in 2005? Assume the survey included 13,400 men and 13,600 women in 1999 and 13,900 men and 13,500 women in 2005, and assume the samples are random and independent. 707 55.9% 53.5% 41.8% 43% 0- 1999 2005 Men Women Identify the null and alternative hypotheses.

State the hypotheses and identify the claim. Compute the test statistic Find the P-value. Make the decision. Write the conclusion. Assume all populations are normally distributed. Test all claims at 0.05. 7. In a random sample of 1020 U.S adults in a recent year, 459 approve of the job the Supreme Court is doing. In another random sample 1510 U.S. adults taken 3 years prior, 694 approved of the job the Supreme Court is doing. Can you support the claim that the proportion of U.S. adults who approve of the job the Supreme Court is doing is less than it was 3 years prior?

use significance level of 0.05 the Trex leg bones are measured in inches. Use the minitab output below The researcher correctly decides to fail to reject the null hypothesis which statement below interprets that decision? A. the population mean is proven to be 175.5? B. The population mean is proven to be different than 175.5? C. The evidence suggests that the population mean is 176.470. D. There is not sufficient evidence to suggest that population mean is different than 175.5? Part B which of the following statement describes the type of error that may have occurred in a hypothesis test outlined above when the researcher makes the correct decision to fail to reject the no hypothesis? A. Reject the nall hypothesis when the nall hyposesis was true B. reject the null hypothesis when the null hypothesis was false. C fail to reject the null hypothesis when the null hypothesis was true. D. fail to reject the null hypothesis when the null hypothesis was false. See which statement correctly…

Use technology to help you test the claim about the population mean, μ, at the given level of significance, a, using the given sample statistics. Assume the population is normally distributed. Claim: μ> 1170; x = 0.08; a=207.79. Sample statistics: x= 1198.51, n = 250 Identify the null and alternative hypotheses. Choose the correct answer below. B. Ho: ≤1198.51 OA. Ho: 21170 Ha: 1170 Ha: 1198.51 OC. Ho: 21198.51 Ha: 1198.51 OE. Ho: 1198.51 Ha: s1198.51 Calculate the standardized test statistic. The standardized test statistic is 2.17. (Round to two decimal places as needed.). Determine the P-value. P=0.015 (Round to three decimal places as needed.) Determine the outcome and conclusion of the test. O D. Ho: H> 1170 Ha: ps 1170 OF. Ho: HS1170 H₂H1170 Reject Ho. At the 8% significance level, there IS enough evidence to support the claim. Time Remaining: 01:29:26
