Step-by-step explanation:
A confidence interval of the mean is a range within is expected to find the population mean, with a certain degree of confidence.
In this case, the population mean is the average price for a lunch for a n=25 sample.
The interpretation of a 95% confidence interval of (14.43,17.57) should be that there is a 95% of confidence that the population mean (average price for a lunch out of a sample of 25 lunches) is within this interval.
0.025/ 0.04
= (0.025* 1000) / (0.04*1000)
= 25/40
= 5/8
= 0.625
Rounded to the nearest hundredth, the final answer is 0.63~
