Poverty thresholds are determined by the U.S. Census Bureau. A poverty threshold represents the minimum annual household income for a family not to be considered poor. In 2004, the poverty threshold for a familyof four with two children under the age of 18 years was $19,157. In 2014, the poverty threshold for a family of four with two children under the age of 18 years was $24,008. Assuming poverty thresholds increase in a straight-line fashion, use the midpoint formula to estimate the povertythreshold of a family of four with two children under the age of 18 in 2009. How does your result compare to the actual poverty threshold in 2009 of $21,756?
Data is collected on the relationship between time spent playing video games and time spent with family. The data is shown in the table and the line of best fit for the data is y^=−0.57x+102.67. Assume the line of best fit is significant and there is a strong linear relationship between the variables.
Video Games (Minutes) 40557085 Time with Family (Minutes) 80726255
According to the line of best fit, what would be the predicted number of minutes spent with family for someone who spent 46 minutes playing video games? Round the answer to one decimal place.
What is the predicted number number of minutes spent with family?
In a regression model if you drop one insignificant variable then a. R ^ 2 will increase and SSE also will increase . None R ^ 2 will decrease and SSE also will decrease . O d R ^ 2 will increase but SSE will decrease . O e R ^ 2 will decrease but SSE will increase .
