conditions have been met. The one-sample t-interval is company's units are in compliance with the request?
calculated to be (2,200, 3,800).
No, because a different sample might give different
results, so no conclusion can be drawn.
O No, because the interval does not contain 4,000, so
the company is not in compliance with the request.
Yes, because the interval representing the mean
number of gallons used per month is entirely below
4.000, it is reasonable to believe the company's
units are in compliance with the request.
O Yes, because the interval representing the mean
number of gallons used per month does not contain
