Answer:
The margin of error is multiplied by
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME= where
- z is the corresponding statistic of the given confidence level
- s is the standard deviation of the sample (or of the population if it is known)
- N is the sample size
Since margin of error is proportional with inverse of ,
if we cut the sample size in half, the margin of error is multiplied by .
