In the American Heart Association journal Hypertension, researchers report that individuals who practice Transcendental Meditation (TM) lower their blood pressure significantly. If a random sample of 228 male TM practitioners meditate for 7.9 hours per week with a standard deviation of 2.25 hours, does that suggest that, on average, men who use TM meditate more than 7.5 hours per week? Quote a P-value in your conclusion. State the null and alternative hypotheses. Hot = 7.5 H₁: > 7.5 (Type integers or decimals. Do not round.) Find the test statistic. The test statistic is 2.68. (Round to two decimal places as needed.) Find the P-value. The P-value is 0.007 (Round to three decimal places as needed.) xample Textbook Clear all Final check

O A myopenmath.com Home - ATI Testing МyOpenMath A shareholders' group is lodging a protest against your company. The shareholders group claimed that the mean tenure for a chief exective office (CEO) was at least 11 years. A survey of 94 companies reported in The Wall Street Journal found a sample mean tenure of 9.5 years for CEOs with a standard deviation of 4 years (The Wall Street Journal, January 2, 2007). You want to formulate and test a hypothesis that can be used to challenge the validity of the claim made by the group, at a significance level of 0.05. Your hypotheses are: H0: μ >11 Ні:д < 11 What is the test statistic for this sample? (Report answer accurate to 3 decimal places.) What is the p-value for this sample? (Report answer accurate to 4 decimal places.) This test statistic leads to a decision to O reject the null O accept the null O fail to reject the null As such, the final conclusion is that there is sufficient evidence to conclude that the population mean tenure for…

A random sample of 160 commercial customers  revealed that 32  had paid their accounts within a month of billing. Can normality be assumed for the sample proportion?

A credit score is used by credit agencies​ (such as mortgage companies and​ banks) to assess the creditworthiness of individuals. Values range from 300 to 850 with a credit score over 700 considered to be a quality credit risk. According to a​ survey, the mean credit score is 705.6. A credit analyst wondered whether​ high-income individuals​ (incomes in excess of​ $100,000 per​ year) had higher credit scores. He obtained a random sample of 34 high-income individuals and found the sample mean credit score to be 724.4 with a standard deviation of 84.4. Conduct the appropriate test to determine if​ high-income individuals have higher credit scores at the α=0.05 level of significance. 1) Find: P-value  2) Make a conclusion regarding the hypothesis.
