The cost of Internet access. The data in Exercise 7.24 show that many people paid $20 per month for Internet access, presumably because major providers such as AOL charged this amount. Do the data give good reason to think that the mean cost for all Internet users differs from $20 per month?

    使用網際網路的費用。資料在練習題7.24中顯示。許多人每各月花費$20元在網際網路的使用上,可能是因為以AOL(American On Line美國境內提供線上加值網路服務的公司)這樣的收費的總額為主要的提供者。此資料是否給予不同網際網路的使用者一個令人滿意的理由去思考平均每各月花費$20元?
