st the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well ase final conclusion that addresses the original claim. Among 2127 passenger cars in a particular region, 240 had only rear license plates. Among 310ommercial trucks, 43 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at agher rate than owners of passenger cars. Use a 0.05 significance level to test that hypothesis:-Test the claim using a hypothesis test.-. Test the claim by constructing an appropriate confidence interval.H₁: P₁ P2OB. Ho: P1 P2H₁: P1 P2OC.

Please see below. Only given one attempt at this. People who sustain a concussion or a traumatic brain injury (TBI) are likely to experience sleep problems. Do these problems persist over time? Researchers recruited a sample of 31 patients who had their first TBI 18 months earlier and a control group of 42 otherwise similar individuals without prior TBIs. They compared sleep duration per 24 hours for the 2 groups. Which test is most appropriate for this scenario? A 2-sample test for means B 1-sample z-test for proportions C 2-sample test for proportions D matched-pairs E 1-sample t-test for means

O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
4. Researchers believe that men are more physically aggressive than women. To test this, researchers ask 20 participants (10 male, 10 female) to rate how aggressive they are on a scale from 1 to 10. Their scores are listed below. Conduct all six steps of hypothesis testing (use p=.05). Be sure to label all six steps. Also, include a concluding statement (which should include the effect size).

Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 44 of the 51 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 97 of the 110 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test?

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Provide all necessary solutions to arrive at the needed answer for each problem. Do not forget to provide proper interpretations for resulting measures and/or tests conducted.
