Consider this quote: “In 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 .03. Because .03 is less than .05, we can conclude that there is a statistically significant difference in preference.” Give a numerical value for each of the following.
a. The p-value.
b. The level of significance, a.
c. The sample proportion.
d. The sample size.
e. The null value.
