1 11/15  that's 73% RETAKE  11 questions were answered correctly. 4 questions were answered incorrectly. Gaurav was conducting a test to determine if the average amount of medication... his patients were taking was similar to the national average. He wants to use a 5% significance level for his test to help ensure that his patients do not receive too little or too much medication. If Gaurav were to conduct a test, what probability value would indicate that his null hypothesis (that there is no significant difference between the amount of medication Gaurav's patients are receiving and the national average) would be rejected?    1.45%  95.78%  5.23%  50.45% UNIT 2 — MILESTONE 2 SCORE 11/15 CONCEPT  Introduction to Significance Levels 2 RATIONALE If we are considering a 5% significance level, then this means that we are accounting for 95% of the data. If we picture this on a normal distribution curve, we would say that 2.5% of the data in the left tail is not accounted for and 2.5% of the data in the right tail is not accounted for. Therefore, probability values that are below 2.5% or above 97.5% indicate that the null hypothesis should be rejected. This is because if the null hypothesis were true for a 5% significance level, then it is very unlikely that we would get probabilities below 2.5% or above 97.5% by accident. Report an issue with this question Given this z-table and the standard normal distribution shown in the graph, which z-score represents a value that is likely to occur?   3.10  -3.33  2.58 [Show More]
