B because it is (2x)(2x) which is equal to 4x^2
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)
Since margin of error is proportional with inverse of
,
if we cut the sample size in half, the margin of error is multiplied by
.
its 2x8x8 is 2069 and add it up
It’s -12 since 12 is already a positive number it has to be opposite so it will have to be a negative number.
