Answer:
Option B.
Step-by-step explanation:
As we know that
Margin of error = Z * standard error
Here , the only way to decrease the value of margin of error is to decrease either the value of z or value of standard error as both are directly proportional to margin of error.
Z-value can be decreased by using lower confidence intervals. Standard error can be decreased by increasing sample size (as given in option B)
The answer is option B as it is using sample size of 50 instead of 35 thus decreasing standard error and ultimately decreasing margin of error.

Step-by-step explanation:
1.
(a) n ≤ 21
(b) n ≥ 5
(c) n > 3/5
2.
(d) n < 14
(e) n ≥ 14
678 is what you have left but if you would put it as a fraction of what you have left now it would be 678/1012... which then take and put it as a decimal which is a form of a mixed number = .6699
Based on the given points, the point that is located on the y-axis is (0,7).
<h3>Which point is on the y axis?</h3>
The point that is on the y-axis should have a coordinate such that x is equal to 0.
This leads to the point being on the y-axis because the nonzero coordinate of the y axis would then have to be placed on the same axis.
The only point with a 0 coordinate is (0, 7) so this is the point that is located on the y-axis.
