This document appears to be a survey with questions about personal hygiene and preferences. It includes 11 questions about things like hand washing frequency, nail clipping frequency, time spent showering, whether they sing in the shower, and preferences on facial hair. The document also analyzes the survey results, including calculating confidence intervals for average responses and comparing affirmative response rates between males and females using a two-sample t-test. The t-test analysis found a high p-value, failing to reject the hypothesis that males answer affirmatively more than females.

11. Comparing affirmative responses Males vs. Females Hypothesis test Hypothesis Ho: Males answer affirmatively more than females. Ha: Males do not answer affirmatively more than females. Conditions/Assumptions Independence: One person’s answer does not affect another Randomness: The sample was chosen at random Less than 10%: The sample is less than 10% of all males and females Nearly Normal: We can assume that the distributions in each question are nearly normal

12. Comparing affirmative responses Males vs. Females Hypothesis test Name the Test We will conduct a 2 sample T test Do the Math = P= 5.870 Conclusion Since we have such a high -value (5.870), we do not reject the null hypothesis which could open up an assumption that Males did answer more affirmatively than females
