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.
