At a 10% significance level, is the performance between the two sample groups significantlydifferent? Based on the data of air pollution in Los Angeles in 2019, the Environmental Protection Agency (EPA)decided to publish a new stricter regulation effective in January 2020 to reduce hydrocarbonpollution. EPA wants to evaluate whether the new regulation makes significant differences in reducingpollution. EPA collects data of monthly hydrocarbon pollution level as follows:JanFeb Mar Apr May JunJul Aug Sep OctNovDec20197.36.05.45.93.95.76.97.66.35.85.15.920205.36.15.65.73.74.76.17.26.45.7 4.95.8

If sample data is such that for a one-tailed test of ? you can reject H0 at the 1% level of significance, can you always reject H0 for a two-tailed test at the same level of significance? Explain your answer? A. Yes. If H0 for a one-tailed test is rejected at the 1% level of significance, it will always be rejected for a two-tailed test at the same level of significance. B. No. If H0 for a one-tailed test is rejected at the 1% level of significance, it will never be rejected for a two-tailed test at the same level of significance. C. Yes. The P-value for the two-tailed test could be greater than 0.01. D. No. The P-value for the two-tailed test could be greater than 0.01.
Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
The table below lists body temperatures obtained randomly selected subjects. The temperatures are categorized according to gender and whether the subject uses drug.
