Answer:
95% of the students have grade point averages that are between 1.76 and 3.28
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 2.52
Standard deviation = 0.38
Using the empirical rule, what percentage of the students have grade point averages that are between 1.76 and 3.28
1.76 = 2.52 - 2*0.38
So 1.76 is two standard deviations below the mean.
3.28 = 2.52 + 2*0.38
So 3.28 is two standard deviations above the mean
By the Empirical rule, 95% of the students have grade point averages that are between 1.76 and 3.28
Point slope form:
m=slope
(x1,y1)
First we need to find the slope using the slope formula:
Given the two coordinates:
<span>(1, 9) and (−1, 11)
Plug them into the slope formula:
</span>
Simplify:
<span>
Now we know that:
m=-1 and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info:
Final answer: y − 9 = −(x − 1)
