9. A dermatologist is interested in whether a new treatment for poison ivy would reduce symptoms more quickly than the current treatment. In general, the current treatment completely eliminates symptoms after an average of 6 days, with a standard deviation of 0.8 days. One randomly selected patient given the new treatment had no symptoms after 5 days. Using the .05 level of significance, is the new treatment faster than the current one? To answer this question use the five steps of hypothesis testing. Hint: Consider if it is a one- tailed or two-tailed test based on the research question. Step 1: Restate the Questions as a Research Hypothesis Population 1: Population 2: Null Hypothesis: Research hypothesis:
