-calculator.php The amount of water consumed each week by Bronx residences is normally distributed. The population mean of water consumption is 120.3 gallons with a standard deviation of 10.0 gallons. Test the claim at the 0.10 significance level that the average amount of water consumed is not 125 gallons with a sample size of 100 residences. What are the hypotheses? Null: u = 125 Alternate: U = 125 Null: H = 125 Alternate: H < 125 Null: u = 125 O Alternate: H> 125 Null: u = 125 Alternate: U 125
