To test the hypothesis that the population standard deviation sigma=13.2, a sample size n=11 yields a sample standard deviation 7.480. Calculate the P-value andchoose the correct conclusion.Your answer:The P-value 0.162 is not significant and so does not strongly suggest that sigma<13.2.The P-value 0.162 is significant and so strongly suggests that sigma<13.2.The P-value 0.014 is not significant and so does not strongly suggest that sigma<13.2.The P-value 0.014 is significant and so strongly suggests that sigma<13.2.The P-value 0.024 is not significant and so does not strongly suggest that sigma<13.2.The P-value 0.024 is significant and so strongly suggests that sigma<13.2.The P-value 0.008 is not significant and so does not strongly suggest that sigma<13.2.The P-value 0.008 is significant and so strongly suggests that sigma<13.2.The P-value 0.295 is not significant and so does not strongly suggest that sigma<13.2.The P-value 0.295 is significant and so strongly suggests that sigma<13.2.

10.2.26-1 Question Help In a survey, 43% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so she randomly selected 180 pet owners and discovered that 72 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a = 0.01 level of significance. Because npo (1-Po) =D 10, the sample size is 5% of the population size, and the sample V the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

1:37 You wish to test the following claim (Ha) at a significance level of a = 0.01. Ho:p = 0.7 Ha:p + 0.7 You obtain a sample of size n = 356 in which there are 261 successful observations. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to three decimal places.) p-value = The p-value is... O less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null O accept the null fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.7. O There is not sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.7. O The sample data support the claim that the population proportion is not equal to 0.7. O There is not sufficient sample evidence to support the claim that…
Assume a significance level of α=0.05and use the given information to complete parts (a) and (b) below. Original claim: More than 51% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0383. a. State a conclusion about the null hypothesis. (Reject H0or fail to reject H0.) Choose the correct answer below. A.Reject H0 because the P-value is less than or equal to α. B. Fail to reject H0 because the P-value is greater than α. C. Fail to reject H0 because the P-value is less than or equal to α. D. Reject H0 because the P-value is greater than α. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? A. There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%. B. The percentage of…

A random sample of 10 independent healthy people showed the following body temperatures (in degrees Fahrenheit): 98.5, 98.2, 99.0, 96.3, 98.3, 98.7, 97.2, 99.1, 98.7, 97.2 Test the hypothesis that the population mean is not 98.6°F, using a significance level of 0.05.
(c) Identify the standardized test statistic. Use technology. z=kjkj (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis, and (e) interpret the decision in the context of the original claim. A. RejectH0. There is sufficient evidence to reject the claim that mean bulb life is at least 743 hours. B. Fail to reject H0. There is sufficient evidence to reject the claim that mean bulb life is at least 743 hours. C. Reject H0. There is not sufficient evidence to reject the claim that mean bulb life is at least 743 hours. D. Fail to reject H0. There is not sufficient evidence to reject the claim that mean bulb life is at least 743 hours.
The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.670 g as required by mint specifications. The sample size is n = 32 and the test statistic is t=-3.177. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.01. State the null and alternative hypotheses. H₁: 5.670 5.670 (Type integers or decimals. Do not round.) The test statistic is. (Round to two decimal places as needed.)
Suppose you wish to conduct a test of the research hypothesis that the median of a population is greater than 78. You randomly sample 15 measurements from the population and determine that 10 of them exceed 78. Set up and conduct the appropriate test of hypothesis at the 0.10 level of significance. Be sure to specify all necessary assumptions. What are the null and alternative hypotheses for this hypothesis test? A. Ho: n = 78 Ha: 178 C. Ho: n=10 Ha:n> 10 Ε. Ηρ:η=78 Ha:n78 Ho: n=10 Hg: η < 10 OF. Ho: n = 10 Ha: 110
Based on information from the Federal Highway Administration web site, the average annual miles driven per vehicle in the United States is 13.5 thousand miles. Assume σ ≈ 500 miles. Suppose that a random sample of 21 vehicles owned by residents of Chicago showed that the average mileage driven last year was 13.2 thousand miles. Would this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance. What are we testing in this problem? (a) What is the level of significance? (b) What sampling distribution will you use? What assumptions are you making? What is the value of the sample test statistic? (c) Find (or estimate) the P-value. (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ?? (e) Interpret your conclusion in the context of the application.
