**Educational Website Text:**Title: Statistical Analysis of Virus Leakage in Laboratory GlovesA study was reported in a newspaper where researchers tested laboratory gloves for virus leakage under stress. The study involved:- 256 vinyl gloves, of which 67% leaked viruses- 256 latex gloves, of which 9% leaked virusesThe aim is to test, at a 0.05 significance level, the claim that vinyl gloves have a higher virus leakage rate than latex gloves. Vinyl gloves are designated as population 1, and latex gloves as population 2.**Hypothesis Testing**We are tasked with identifying the null and alternative hypotheses for this scenario:- **Null Hypothesis ($H_0$)**: Assumes no difference in leakage rates between vinyl and latex gloves, or that vinyl gloves have a leakage rate equal to or less than latex gloves. - **Alternative Hypothesis ($H_1$)**: Assumes vinyl gloves have a greater leakage rate than latex gloves.**Options for Hypotheses:**A. $H_0: p_1 = p_2$; $H_1: p_1 > p_2$ B. $H_0: p_1 = p_2$; $H_1: p_1 < p_2$ C. $H_0: p_1 = p_2$; $H_1: p_1 \neq p_2$ D. $H_0: p_1 \geq p_2$; $H_1: p_1 = p_2$ E. $H_0: p_1 < p_2$; $H_1: p_1 = p_2$ F. $H_0: p_1 > p_2$; $H_1: p_1 = p_2$The correct choice should align with testing whether vinyl gloves have a statistically significant higher leakage rate than latex gloves.

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.
