Answer:
The graph represent a scatter plot between variable A on the horizpntal line and the variable B on the vertical line.
A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.
As shown by graphinf a line through the maximum number of points, balancing about an equal number of points above and below the line, we can deduce that:
<u>The line of best fit drops from left to right, so the variables have a negative correlation. </u>

Answer:
The test statistic is 
Step-by-step explanation:
We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.
At the null hypothesis, we test if the proportion is 80%, that is:
At the alternate hypothesis, we test if the proportion is more than 80%, that is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
80% is tested at the null hypothesis:
This means that 
A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.
This means that 
The test statistic is
The test statistic is
Answer:
When we have a number like:
1.0x10^n
To rewrite this in standard form, we need to:
if n is positive, we move the decimal point n times to the right, adding zeros when necessary.
1.0x10^3
n = 3. then we add 3 zeros between the one and the decimal point, this is:
1.0x10^3 = 1000
if n< 0, then we move the decimal point n times to the left.
If we had:
1.0x10^-3
We move the decimal point 3 times to the left, adding zeros as this is needed.
1.0x10^-3 = 0.001
if n = 0, we have:
1.0x10^0 = 1.0
Now let's rewrite all the given numbers:
A) 3.4x10^-1 = 0.34
B) 1.36x10^6 = 1360000
C) 7.9x10^0 = 7.9
D) 2.4x10^5 = 240000
E) 5.21x10^-3 = 0.00521
F) 4.3x10^-2 = 0.043
