Answer:
ME = z*s /√n
Step-by-step explanation:
The margin of error is obtained as the product of the critical value of the distribution at a certain α-level and the standard error :
The critical value = Z*
The standard error = standard deviation / √sample size
Standard deviation = s
Sample size = n
Margin of Error = z * s/√n
B
If you multiply both 2.3 x 1.98, you get 4.55
i dont know man
...
It should be $378. sorry if I am wrong.
