The scatter plot below shows the number of cups of coffee some adults had in a day and the number of hours of uninterrupted sleep they got at night: Based on the plot, which conclusion is correct?

OpenStudy (henrietepurina):

OpenStudy (henrietepurina):

The more cups of coffee a person consumes, the more hours of sleep the person gets at night. The more cups of coffee a person consumes, the fewer hours of sleep the person gets at night. The fewer cups of coffee a person consumes, the fewer hours of sleep the person gets at night. There is no relationship between the number of cups of coffee a person consumes and the number of hours of sleep.
