To determine the answer to this item, we first calculate the z-scores of the given data point through the equation,
z-score = (data point - mean) / standard deviation
For 5:
z-score = (5 - 7) / 1.7 = -1.176
This translates to a percentile of 11.97.
For 10:
z-score = (10 - 7) / 1.7 = 1.76
This translates to a percentile of 96.08.
The difference between the percentiles is 84.11. Thus, 84% of the students sleep between 5 to 10 hours.

Answer:
y = 4/7 - 4
Step-by-step explanation:
Slope = (-4-0) / (0 - 7) = -4/-7 = 4/7
y-intercept: -4 - (4/7)(0) = -4
