Answer: The maximum error = $105.76.
Step-by-step explanation:
Formula to find the maximum error:
, where n= sample size.
= Population standard deviation
z*= Critical value(two-tailed).
As per given , we have
n= 35
For 98% confidence , the significance level =
By z-table , the critical value (two -tailed) =
Now , the maximum error =
Hence, With 98% confidence level , the maximum error = $105.76.
