Answer:
None of the answer options are correct.
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.
Answer:
5 sqrt2.
Step-by-step explanation:
5 sqrt 8 - sqrt 18 - 2 sqrt 2
= 5 sqrt(4*2) - sqrt(9*2) - 2 sqrt2
= 5 sqrt4*sqrt 2 - sqrt 9*sqrt 2 - 2 sqrt2
= 10 sqrt2 - 3 sqrt2 - 2 sqrt 2
= 5 sqrt2.
