Suppose you were interested in testing the relationship between type of drug and relief from head ache. For this example, assume you had counts of the number of persons taking two drugs (say, Aspirin and Tylenol) and their subsequent response in terms of headache was coded into two groups: "went away after taking the drug" or "did not go away". In this case, would you use a chi-square test of goodness of fit or a test of independence? A. Goodness of fit B Test of independence

option B is correct

Step-by-step explanation:

since here we want to see if there is a relationship between two variables (taking different drug and headache levels_)

option B is correct

B. test of independence

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

12.5 feet
