Step-by-step explanation:
The equation of a line is , where
is the slope and
is the
intercept.
We know that the line pass through the point (1,1) and the slope is 2.
Then,
We have to find .
If we replace the point (1,1) in we will obtain
.
Then,
The y intercept then is -1, this means that when x=0, y=-1.
We have the point (0,-1).
Now to obtain another point we have to replace with y=0.
We have the point
Now that we have to points, we have to place them in the cartesian coordinate system. And then draw the line.
Answer:
0.9168
Step-by-step explanation:
From the data given:
Mean = 110
standard deviation = 5
Let consider a random sample n =49 which have a mean between 109 and 112.
The test statistics can be computed as:
= -1.4
Thus; P(109 < < 112) = P( - 1.4 < Z < 2.8)
= P(Z < 2.8) - P( Z < -1.4)
= 0.9974 - 0.0806
= 0.9168
First, compute the mean: 
Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445
Next we'll take the mean of these deviations:
The mean absolute deviation of your data is 13.8517
Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445
Next we'll take the mean of these deviations:
The mean absolute deviation of your data is 13.8517
