The scatter plot of William's sleeping and waking hours is likely to show a negative correlation, as more sleeping hours would generally mean fewer waking hours, which should reflect in a negative correlation coefficient significantly different from zero.
William's scatter plot displaying the relationship between sleeping hours (x) and waking hours (y) for each day likely shows a negative correlation. This is because as the number of sleeping hours increases, one would expect the number of waking hours to decrease, and vice versa, since there is only a fixed number of hours in a day (usually 24 hours). In a similar example, there is a negative correlation between tiredness and hours of sleep, where more sleep is associated with less tiredness. The correlation coefficient in this relationship should be significantly different from zero. If the coefficient is close to -1, it indicates a strong negative correlation where the data points would closely follow a straight downward line on the scatter plot.
