- Choosing the alpha level for a hypothesis test allows researchers to control the probability of committing a type II error. true vs. false? there is one expert answer on bartleby ("true") but has a thumbs down attached to it, which leads me to believe it is incorrect? thanksplease answer following question attachedHelp Answer this thankyou!
- Q3 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 2125 passengers cars in a particular region, 229 had only rear license plates. Among 326 commercial trucks, 47 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 passengers cars. Use a 0.01 significance level to test that hypothesis. A. Identity the nulls and alternative hypotheses B. Identify the test statistic ( round to two decimal places as needed) C. Identify the p- values (round to two decimal places as needed ? State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. A. Fail to reject Ho. There is not sufficient evidence to support the claim that commercial trucks owners…Does more education lower a person’s level of prejudice? The number of years of education and the score on a prejudice test for ten people is given in the following table. Higher scores on the test indicate more prejudice. Years of Education: 12, 15, 14, 13, 18, 10, 16, 12, 10, 4 Score of Prejudice Test: 1, 6, 2, 3, 2, 4, 1, 5, 5, 10 Conduct a hypothesis test to determine if there is a significant linear correlation between the two variables. If there is a significant linear correlation between the variables, determine the regression equation. There is a significant correlation between the variables and the regression equation is y' = 10.5 - 0.532x There is a significant correlation between the variables and the regression equation is y' = - 0.532 + 10.5x There is not a significant correlation between the variables, so the regression equation should not be determined. There is a significant correlation between the variables and the regression equation is y' = 16.509 - 1.054xplease answer in text form and in proper format answer with must explanation , calculation for each part and steps clearly

- Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%Use technology to find the P-value for the hypothesis test described below The claim is that for a smartphone carrier's data speeds at airports, the mean is p= 11.00 Mbps. The sample size isn=25 and the test statistic is t= 1778 Pvalue= =(Round to three decimal places as needed)Choosing the alpha level for a hypothesis test allows researchers to control the probability of committing a type II error.
