Depending on your school commute on your way to to campus, you regularly stop at one of two of your favorite coffee shop locations "Fresh Pots!". You begin to suspect that one location is inconsistently producing their coffee by watering them down or over brewing them. You develop a hypothesis to test your claim that one location is producing inconsistent products, which of the following is the correct description for the type of hypothesis test you should perform? Note: Each location has the same three brewed coffee roasts.
Select one:
a. One-tailed hypothesis test with unpaired data
b. One-tailed hypothesis test with a difference in means
c. Two-tailed hypothesis test with a difference in means
d. Two-tailed hypothesis test with paired data
e. The data is not normal and can not be tested with the information provided
I guess it is c.
Am I right?
I also guessed C and it's wrong.
I think I'm in your class lol
Based on the information provided, the correct description for the type of hypothesis test you should perform is a Two-tailed hypothesis test with a difference in means.
The reason for this is because you suspect that one location is producing inconsistent coffee products, which implies a difference in means between the two locations. The two-tailed test is appropriate because you are not sure whether the suspected location is producing higher or lower quality coffee; you simply suspect that there is a difference.
To perform this hypothesis test, you would collect data on the coffee produced at both locations, such as the strength of the coffee or any other measurable quality. Then, you would calculate the means of the two locations and analyze the data using statistical methods to determine if there is a significant difference between the means.
Therefore, the correct answer is c. Two-tailed hypothesis test with a difference in means.
