Answer:
2.5% of IQ scores are no more than 65
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 = 95
Standard deviation = 15
Using the empirical rule, what percentage of IQ scores are no more than 65?
65 = 95 - 2*15
So 65 is two standard deviations below the mean.
By the Empirical Rule, 95% of the measures are within 2 standard deviation of the mean. Of those 5% which are not, 2.5% are more than 2 standard deviations above the mean and 2.5% are more than 2 standard deviations below the mean.
So 2.5% of IQ scores are no more than 65
The answers are 0 and 2
This can be found by looking at the x axis and finding every point where the line crosses
Answer:
24sq.ft
Step-by-step explanation:
<h3>
Area of a parallelogram = Base*Height</h3>
Here,
→Base = 6ft, Height = 4ft
→ 6*4ft
→24sq.ft
<h3 /><h3>
While writing area of a figure, we have to express the area in sq which means square</h3>
