Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2159 passenger cars in a particular region, 245 had only rear license plates. Among 326 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.05 significance level to test that hypothesis. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. O A. Ho: P1 < P2 H1:P1 = P2 О В. Но: Р1 3P2 H1: P1 P2

A sample of six college basketball player had an average weight of 217 pounds with a sample standard deviation of 10 pounds. Find the 95% confidence interval of the true mean weight of all basketball player. What is the Degree of Freedom, Critical Value and Confidence Interval? With solution please. What is the sample mean?
Hi Team, Please provide answer for part B as well, Thanks a lot for all the help.
If a research study in biomedical field found a moderate negative and statistically significant relationship between two variables, which of the following statistical parameters would you expect to see? -.48, p<.05 -48, p<.01 -.68, p<.01 1, p<.01
Please help sole with all questions, my answer are wrong. It’s statistics
Choose a type of confidence interval: one proportion z, two proportion z, one sample t, two sample t, or paired t. Can someone create one or a few original practice problems that could be solved using that test and show the full solution? If you can be thorough in your explanation it would be great. I need some new ones to work on and compare my work to the answers. Thanks
Does the confidence interval not change for population proportion vs sample proportion
*PLEASE show in excel A different investigator conducts a second study to investigate whether there is a difference in mean PEF in children with chronic bronchitis as compared to those without. Data on PEF are collected and summarized below. Based on the data, is there statistical evidence of a lower mean PEF in children with chronic bronchitis as compared to those without? Run the appropriate test at a=0.05. Group Number of Children Mean PEF Std Dev PEF Chronic Bronchitis 25 281 68 No Chronic Bronchitis 25 319 74 Step 1. Set up hypotheses and determine level of significance. Ho: H1: alpha: Step 2. Select the appropriate test statistic and give its formula. Step 3. Set up decision rule. Step 4. Compute the test statistic Step 5. Conclusion.
could you please tell me how to explain to a friend who does not know anything about statistics the relationship between the confidence level expressed as a confidence interval and the level of significance in hypothesis testing. Illustrate the relationship using either the critical value or the p-value approach.thanks
Please help and explain the confidence interval statistic problem. Thanks 2
