Statistics

Can the consumption of water in a city be predicted bytemperature? The following data represent a sample of a day’s waterconsumption and the high temperature for that day. Water Use(millions of gallons) Temperature (degrees Fahrenheit) 219 103ο 5639 107 77 129 78 68 50 184 96 150 90 112 75

a. Develop a least squares regression line to predict the amountof water used in a day in a city by the high temperature for thatday. .

b. What would be the predicted water usage for a temperature of100ο?

c. Evaluate the regression model by calculating se, bycalculating r2, and by testing the slope. Let alpha = .01. *(Roundyour answer to 2 decimal places.) **(Round the value of SSE to 4decimal places. Round your answers to 3 decimal places.)

a. y Overscript Ì‚ EndScripts = plus x (Do not round theintermediate values. Round your answers to 4 decimal places.)

b. y Overscript Ì‚ EndScripts = (Do not round the intermediatevalues. Round your answers to 2 decimal places.)

c. se = **

r2 = *

Observed t = *
