Based on the hypotheses you stated, explain whether the researcher should conduct a one-tailed or two-tailed test.

Scenario - The researcher wants to conduct a correlation to investigate further if there is a relationship between hours of sleep and reaction time. For this experiment, participants are allowed to sleep as much as they would like (that is, they are not assigned to sleep any specific number of hours). When 20 participants come to their appointment time, they report to the researcher how many hours of sleep they had the previous night. The researcher then tests their reaction times.

Null Hypothesis- There is no correlation between the amount of sleep obtained and the participants driving reaction time.

Alternative - There will be a correlation between the amount of sleep obtained and the participants reaction time
