n a recent survey, 61 out of 100 consumers reported that they preferred plastic bags instead of paper bags for their groceries. If there is no difference in preference in the population, the chance of such extreme results in a sample of this size is about 0.03. Because 0.03 is less than 0.05, we can conclude that there is a statistically significant difference in preference. 1. What is the p-value? A) 0.39 B) 0.03 C) 0.61 D) 0.05 2. What is the level of significance? A) 0.39 B) 0.61 C) 0.05 D) 0.03 3. What is the sample proportion? A) 0.05 B) 0.39 C) 0.03 D) 0.61 4) What is the sample size? A) 100 B) 61 C) 39 5) What is the null value? A) 0.05 B) 0.39 C) 0.03 D) 0.61 E) 0.50 Solution 1.B) 0.03 2. C) 0.05 3. D) 0.61 4. A) 100 5. E) 0.50.
