We know for our problem that Rachel makes $10 per hour. Since
represent the number of hours that she works, 
will be the total amount that she will make for working hours. We also know that she sells bracelets for $5 each. Since 
represents the number of of bracelets that she sells, 
will be her total revenue for selling bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of and must be equal or greater than 200:

Answer:
D) The z-statistics would be different.
Step-by-step explanation:
Confidence Interval can be calculated using M±ME where
- M is the sample mean
- ME is the margin of error from the mean
An margin of error (ME) from the mean can be calculated using the formula
ME= where
- z is the corresponding z-statistic in the given confidence level
- s is the population standard deviation
- N is the sample size
If 95% and 98% confidence intervals were calculated from the same sample data, then M, s and N are same.
is called standard error. Since s and N are same the standard errors would also be same.
But, two tailed z-statistic for 95% confidence level is ≈1.96 where for 98% it is ≈2.33
