<u>Graph Reading</u>
Line graphs are visual ways of representing two or more data sets and their interrelation.
Graphs are pictures that show how one variable changes in relation to another.
Learning to properly read graphs is a matter of interpreting which pieces of information are useful.
The graph (in the red drawing) shows how sales of ice lollies changed in time. By February, the sales were about 4 units and by August sales were up to 80 units.
This means an increase of 80 - 4 = 76 units.
The sales of ice lollies increased by 76 units between February and August
The answer is A because you have to use the process of substitution
Answer:
B (0.312, 0.364)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
For this problem, we have that:
1289 randomly selected American adults responded to this question. This means that 
.
Of the respondents, 436 replied that America is doing about the right amount. This means that 
.
Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party.
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval is:
B (0.312, 0.364)
Hey there! :D
That's like saying:
-2*-2*-2
-2*-2=4
4*-2= 8
"D" -8 <== the answer
I hope this helps!
