Answer:
True
Step-by-step explanation:
The margin of error of a confidence interval is given by:

In which z is the critical value related to the confidence level,
is the standard deviation of the population and n is the size of the sample.
So as n increases, the margin of error decreases, that is, the interval gets narrower.
The students could produce a narrower confidence interval by increasing the sample size to 100.
From the explanation above, the answer is true.

For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.
For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.
