The side effects of a new drug are being tested against a placebo. A simple random sample of 565 patients yields the results below. At a significance level of α = 0.05, is there enough evidence to conclude that the treatment is independent of the side effect of nausea? Result Drug Placebo TOTAL Nausea 36 13 49 No nausea 254 262 516 TOTAL 290 275 565
Use Excel to determine whether the variables mentioned in the two problems below are independent or not. Clearly state the 4 steps in Hypothesis Testing as discussed:
Step 1: The hypotheses are written in words.
Step 2: Find the alpha in the problem
Step 3: Make a screenshot of the Excel calculations are results as shown in the video.
Step 4: Make a decision based on the value found in Step 3 and make a conclusion.
2. The side effects of a new drug are being tested against a placebo. A simple random sample of 565 patients yields the results below. At a significance level of α = 0.05, is there enough evidence to conclude that the treatment is independent of the side effect of nausea?
| Result | Drug | Placebo | TOTAL |
| Nausea | 36 | 13 | 49 |
| No nausea | 254 | 262 | 516 |
