-------------------------------------------------------------------------------- A vat holds 20 cubic feet of liquid and is initially full. Water containing 6 grams of salt per cubic foot is being poured into the vat at the rate of 4 cubic feet per minute, and is instantly mixed. The mixed liquid is draining from the vat at 4 cubic feet per minute, so the vat is always full. Let y(t) denote the number of grams of salt in the vat after t minutes. Write the differential equation...

The mean consumption of water per household in a city was 1212 cubic feet per month. Due to a water shortage because of a drought, the city council campaigned for water use conservation by households. A few months after the campaign was started, the mean consumption of water for a sample of 92 households was found to be 1167 cubic feet per month. The population standard deviation is given to be 220 cubic feet. a. Find the p-value for the...
