The Amercian Water Works Association reports that the per capita water use in a single family home is 69 gallons per day. A new housing development agency had builders intall more efficient water fixtures and conducted a survey of residents. 36 residents responded and the sample mean water use was 64 galons with a SD of 8.8 gallons per day. At the 0.10 level of significance, is that enough evidence to conclude that these residents surveyed are using less water on average ?

The corrosive effects of various soils on coated and uncoated steel pipe was tested by using a dependent sampling plan. The data collected are summarized below, where d is the amount of corrosion on the coated portion subtracted from the amount of corrosion on the uncoated portion.
