True
Step-by-step explanation:
Confidence interval for banking service in a given confidence level can be calculated as M±ME where
- M is the mean banking service in the sample and
- ME is the Margin of Error
margin of error (ME) is calculated using the formula
ME=
where
- t is the corresponding statistic in the given confidence level
- s is the standard deviation of the sample(or of the population if it is known)
t-statistic for 99% confidence level is always bigger than 95% confidence level which makes Margin of Error bigger and thus confidence interval wider.

The total earnings for the two days is (15+d) dollars
Step-by-step explanation:
The total earning for the two days can be expressed as;
C=M+T
where;
C=total earnings for the two days
