Question:
A public water supply official claims that the average household water use is greater than 350 gal/
day. To test this assertion, a random sample of 200 households was questioned. If the random sample showed an average use of 359 gal/day and a standard deviation of 35 gal/day, would it be safe to conclude at the 1% level of significance that water use is greater than 350 gal/day?
