Suppose that IQ scores have a bell-shaped distribution with a mean of 104
104 and a standard deviation of 17.Using the empirical rule, what percentage of IQ scores are between 70 and 138?
Answer:
68%
Step-by-step explanation:
The empirical rule basically states that 68% of the data falls within one standard deviation from the mean, 95% of the data falls within two standard deviations from the mean, and 99.7% of the data falls within three standard deviations from the mean.
So to find the percentage of IQ scores between 70 and 138, you need to find how far each of these numbers is from the mean in terms of the standard deviation.
If you subtract the standard deviation from the mean, you receive 87, and if you add the standard deviation to the mean, you receive 121.
This means that both of these numbers are within one standard deviation from the mean meaning according to the empirical rule, that means 68% of the IQ scores are between 70 and 138.
good luck, i hope this helps :)
Answer:
99.7%
Step-by-step explanation:
According to the empirical rule, approximately 99.7% of data values lie within 3 standard deviations of the mean.
Suppose we have a regression line where the intercept is 0.24 and the slope is 0.87. Our variable of interest is x. Suppose the standard errors for the intercept 0.02 and the slope is 0.07. What is the upper estimate for a one unit increase in the x variable according to the margin of error
Answer:
Step-by-step explanation:
Margin of Error = Zcritical * Standard error

For the following sample of n 5 10 scores:
a. Assume that the scores are measurements of a discrete variable and find the median.
b. Assume that the scores are measurements of a continuous variable and find the median by locating the precise midpoint of the distribution.
Scores: 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Answer:
Step-by-step explanation:
Given that:
scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Since the scores are already in ascending order; then the median which is the middle number will be:
median = (5th term + 6 term)/2
median = (5+5)/2
median = 10/2
meian = 5
b)
Use the cumulative percentage table
X frequency cumulative frequency cumulative percentage
2 1 1 10%
3 1 2 20%
4 2 4 40%
5 3 7 70%
6 2 9 90%
7 1 10 100%
fraction = the no. required to reach 50%/ no. in that interval
= 1/3
Since we have a total of 4 boxes when we reach the value of 4.5
The median of the continuous variable = 4.5 + (1/3)
The median of the continuous variable = 4.833
The median of the continuous variable ≅ 5
Answer:
Step-by-step explanation:
Given that:
scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7
Since the scores are already in ascending order; then the median which is the middle number will be:
median = (5th term + 6 term)/2
median = (5+5)/2
median = 10/2
median = 5

2. The value, v, of the hat is less than $9.
what is the inequality
Answer:
v < 9
Step-by-step explanation:
Since the value of the hat is less than 9, we will use a less than sign.
In the inequality, the less than sign has to be in front of 9.
So, put this together:
v < 9
The inequality is v < 9

Solve for T
48 = - 12t
t =
Answer:
t=-4
Step-by-step explanation:
48/-12
Answer:
48=-12t
We simplify the equation to the form, which is simple to understand
48=-12t
We move all terms containing t to the left and all other terms to the right.
+12t=-48
We simplify left and right side of the equation.
+12t=-48
We divide both sides of the equation by 012 to get t.
t=-4

find sin θ and cos θ if tan θ= 1/4 and sin 0>0.
Answer:
[tex]\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}[/tex]
[tex]\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }[/tex]
Step-by-step explanation:
We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.
First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:
[tex]h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}[/tex]
So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.
Then it follows that:
[tex]\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}[/tex]
And that:
[tex]\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }[/tex]
