Internet Use The following graph shows the percentage of U.S. households using the Internet at home in 2010 as a function of household income (the data points) and a logistic model of these data (the curve).49
The logistic model is
a. According to the model, what percentage of extremely wealthy households used the Internet?
b. For low incomes the logistic model is approximately exponential. Which exponential model best approximates
c. According to the model, 50% of households of what income used the Internet in 2010? (Round the answer to the nearest $1,000.)
