Ans:
The p-value is the probability of getting a test statistic at least as extreme as the one representing the sample data,assuming that the null hypothesis is True.
The P value is the probability of finding the observed, or more extreme, results when the null hypothesis of a study question is true,the definition of 'extreme' depends on how the hypothesis is being tested.
The p-value is the probability of getting a test statistic at least as extreme as the...
The accompanying data table lists the magnitudes of 50 earthquakes measured on the Richter scale. Test the claim that the population of earthquakes has a mean magnitude greater than 1.00. Use a 0.01 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and conclusion for the test. Assume this is a simple random sample.
The accompanying data table lists the magnitudes of 50 earthquakes measured on the Richter scale. Test the claim that the population of earthquakes has a mean magnitude greater than 1.00.

For each question Identify the test statistic(round two decimal places) Identify the P-value(round three decimal places) Use the pulse rates in beats per minute (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 75 bpm. Use a 0.05 significance level. : Click the icon to view the pulse rate data Assuming all conditions for conducting a hypothesis test are met, what are the null...
Use the Wilcoxon Signed-Ranks Test. If software is needed, please use Excel. I only have Excel and a TI-30X calculator. Part a) Use Wilcoxon Signed-Ranks Test for the claim about the median of a population..."Earthquake Magnitudes." Part b) Use Wilcoxon Signed-Ranks Test for the claim about the median of a population..."Earthquake Depths." Use the Wilcoxon Signed-Ranks Test. If software is needed, please use Excel. I only have Excel and a TI-30X calculator. Part a) Use Wilcoxon Signed-Ranks Test for the...
can you find the test statistic and p value please? In a test of the effectiveness of garlic for lowering cholesterol, 61 subjects were treated with raw gari. Cholesterol levels were measured before and ster the treatment. The changes before minus ather) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.4 and a standard deviation of 232 Use a 0.05 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol...
Question 7 (1 point) Which of these is NOT what the P-value is? The probability of getting the sample results you did or something even more extreme if H-null is actually true. The probability of getting a type I error. The area in the tail(s) beyond the test statistic, Question 8 (1 point) What is the significance level of a hypothesis test? How important and useful the test is 1-alpha (the complement of alpha) The probability of rejecting the null...
Use the Sign Test. If software is needed, please use Excel. I only have Excel and a TI-30X calculator. Use the Sign Test. If software is needed, please use Excel. I only have Excel and a TI-30X calculator. Appendix B Data Sets. In Exercises 13-16, refer to the indicated data set in Appendix B and use the sign test for the claim about the median of a population. 13. Earthquake Magnitudes Refer to Data Set 21 "Earthquakes" in Appendix B...
For the folowing claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 119. Sample data: n 11, x 117, s 14. The significance level is ?-005 Click the icon to view a table of critical t-values. a. Choose the correct null hypothesis (Ho) and altenative hypothesis...
A hypothesis test is conducted to test the null hypothesis that the mean is less than 12. Use a 0.01 level of significance. What type of test is this? Right tail Two tail Left tail What is the critical value? 2.33 -2.33 1.78 correct answer is not given Suppose the test statistic was -2.50 What is the conclusion? Fail to reject Ho. There is not sufficent evidence to support the claim that the mean is less than 12. Reject Ho....
