URGENT. The Turkish Water Works Association reports that the per capita water use in a single-family home followed a normal distribution with mean µ=64 liters and standard deviation σ=9.4 liters per day. Mesa Mozaik is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-nine owners responded, and the sample mean water use per day was 60 liters. At the 0.01 level of significance, is...

The analysis of a random sample of 550 households in a suburb of a large city indicates that a 92% confidence interval for the mean family income is ($45,700, $59,150). Could this information be used to conduct a test of the null hypothesis H0: µ = 44,000 against the alternative hypothesis Ha: µ ≠ 44,000 at the α = 0.08 level of significance? Yes, because $44,000 is not contained in the 92% confidence interval, the null hypothesis would be rejected...

The mean family income for a random sample of 600 suburban households in Loganville shows that a 95 percent confidence interval is ($43,100, $59,710). Alma is conducting a test of the null hypothesis H0: µ = 42,000 against the alternative hypothesis Ha: µ ≠ 42,000 at the α = 0.05 level of significance. Does Alma have enough information to conduct a test of the null hypothesis against the alternative? A No, because the value of σ is not known B...
