A researcher hypothesizes that there is a strong negative correlation between the number of alcoholic drinks consumed the night before a major test and the score on that test. The two variables (amount of alcohol and test score) are listed below. Enter the data into Excel, determine the correlation, and explain whether the researchers hypothesis is correct. The correlation coefficient of number of drinks and test score is Explain what this correlation coefficient means (i.e., provide the strength and direction). What can you conclude about the relationship between the number of drinks and test score? (Describe in lay-mans terms the relationship between the variables) Comment on the validity of the researcher s hypothesis. Was the hypothesis correct? Incorrect? Consider the correctness of both strength and direction of the researcher s predictions about the relationship between number of drinks and test scores.
