Using the Empirical Rule, the interval that contains 68% of the scores is [81.5, 90.5].
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
68% of the scores are within 1 standard deviation of the mean, hence the bounds of the interval are:

Answer:
y = -4/3x - 1/3
Step-by-step explanation:
-3/2x+2y=-7
2y = 3/2x - 7
y = 3/4x - 7/2
y = -4/3x + b
5 = -4/3(-4) + b
5 = 16/3 + b
-1/3 = b
