A linear regression model predicting the linear effects of the amount of water used in growing...
A linear regression model predicting the linear effects of the amount of water used in growing almonds is developed below:
y = 56+10x
The water data has a range of data from 5 to 90 and is in units of 100 gallons, and the almond data is in pounds.
According to the model, how many acres will grow if 1000 gallons is used
Homework Answers
1000 gallons means 10 ( 100 gallons )
y = 56 + 10x
y = 56 + 10*10
y = 56 + 100
y = 156
almonds = 156 pounds

1. The following data shows the number of miles driven and advertised price for 11 used Honda CR-Vs from the 2005- 2009 model years (prices found at www.carmax.com). The scatterplot below shows a strong, negative linear association between number of miles and advertised cost. The line on the plot is the regression line for predicting advertised price based on number of miles. Cost (dollars) 17998 16450 14998 13998 14599 14988 13599 14599 11998 14450 10998 18 16 o 14 12...

Imagine that you are a consultant who is building a statistical model to predict how long a customer will remain with a firm (i.e., customer retention). Research demonstrates that both consumer satisfaction and calculated brand commitment should help predict customer retention. Consumer satisfaction is defined as a customer’s overall evaluation of the performance of a product or service to date.78 Calculated brand commitment is a consumer’s dependence on a brand’s benefits due to a lack of choices or switching costs.79...
