Broadband internet and poverty rates-Data from the 2019 American Community Survey records the percent of the population below the poverty level (Poverty) and the percent of households that have a broadband internet subscription (Broadband) for each county in the United States. Grant is a statistics student. For a class project, he selects a random sample of 120 US counties for which this data is recorded and constructs a linear regression model using Poverty as the explanatory variable and Broadband as the response variable. A scatterplot of Grant's data is shown. US County Data 2019 Grant uses statistical software to fit a linear model to the data. A summary of that model fit is given below: Coefficients Estimate Std Error t value Pr(> [t (Intercept) 94.93006 1.47348 64,42596 2e-16 -1.04708 0.09435 -11.09797 2e-16 Poverty Residual standard error: 5.52424 on 118 degrees of freedom Multiple R-squared: 0.51071, Adjusted R-squared: 0.50656 1. Use the computer output to write the estimated linear regression equation for predicting Broadband from Poverty. y= Interpret the slope and intercept of the linear regression model: 2. An increase of 1 point in Poverty is associated with a(n) ? 3. A county with a Poverty value of 0 would have an expected value of ✓ of in Broadband. in Broadband. 10 5 Percent of population below the poverty level
