When looking at the percentage of patients whose symptoms were relieved after taking a placebo, a scientist sees a 20% success rate. The success rate of patients whose symptoms were relieved after taking a new composite drug was 30%. The scientist determines that the margin of error is 10%, which indicates that the new drug had no statistically significant positive effect.

Question
When looking at the percentage of patients whose symptoms were relieved after taking a placebo, a scientist sees a 20% success rate. The success rate of patients whose symptoms were relieved after taking a new composite drug was 30%. The scientist determines that the margin of error is 10%, which indicates that the new drug had no statistically significant positive effect. In which stage of the engineering process is this scientist?A.Looking for future improvementsB.Evaluating test resultsC.Identifying a needD.ScreeningSUBMITarrow_backPREVIOUS
Solution
To determine the stage of the engineering process the scientist is in, let's break down the information provided:
- The scientist has observed the success rates of two treatments: a placebo (20%) and a new composite drug (30%).
- The scientist has calculated the margin of error to be 10%.
- Based on the margin of error, the scientist concludes that the new drug does not have a statistically significant positive effect.
Given these points, the scientist is analyzing the data and drawing conclusions about the effectiveness of the new drug. This activity aligns with the stage of evaluating the outcomes of an experiment or test.
Therefore, the scientist is in the stage of:
B. Evaluating test results

In a clinical trial I, a Drug X was tested with placebo and it was found to be better than the placebo with a p< 0.05. In clinical trial II, a Drug Y was tested with placebo and it was found to be better than the placebo with a p < 0.01. Which of the following statement is correct: Drug Y is better than drug X We can say with more confidence that drug Y is better than the placebo Drug X is effective 95% of the time and Drug Y is effective 99% of the time Drug X fails in the treatment 5% of the time
QUESTION 3 Students were given different drug treatment before revising for their examinations. some were given a memory drug, some a placebo and others no treatment. the exam scores (%) are shown for the three groups: MEMORY DRUG: 70,77,83,90,97. Mean: 83.40, variance: 112.40 PLACEBO: 37,43,50, 57, 63. mean:50.00, variance: 109.00 NO TREATMENT: 2, 10, 17, 23, 30 . Mean: 16.60, Variance: 112.30 GRAND MEAN: 50.00 GRAND VARIANCE: 892.14 (A) Carry out an analysis of variance to determine wether the treatments have different effects on the performance of the student (use alpha = 0.05)
A scientist wants to create a drug that will kill cancer cells upon absorption in the intestines. In order for the drug to work effectively, it must not be absorbed until it reaches the intestines.
