Problem 54

A standard drug is known to be effective in 72 percent of the cases in which it is used to treat a certain infection. A new drug has been developed and testing has found it to be effective in 42 cases out of 50. Is this strong enough evidence to prove that the new drug is more effective than the old one? Find the relevant p-value.

Step-by-Step Solution:
Step 1 of 3

1.1 Variable: a characteristic that varies from person to person, object to object, etc. Categorical: outcome/answer is a catagory Quantitative: outcome/answer is a number that represents a quantity Explanatory: explains the change in the response variable Response: changes based on the explanatory variable Case: is who/what we record the variable about Ex: The individual movie title in worksheet 1.1 1.2 Population: The whole group of specific individuals you are interested Sample: A small group drawn from the larger population Statistical Inference: How the sample data reflects on the greater population Sampling bias: occurs when the method of selecting the sample causes the sample to differ in some relevant way from the populat
