Suppose the Federal Communications Commission would like to compare the percentage of the population with access to broadband Internet between Alaska, California, Virginia, and New Mexico. A random sample of 270 adults from these four states was selected and their Internet availability was recorded. These results are shown in the following table.

a. Using α = 0.05, perform a chi-square test to determine if the percentage of the population without access to broadband Internet between Alaska, California, Virginia, and New Mexico differs.

b. Determine the p-value for the chi-square test statistic using Excel and interpret its meaning.

c. Verify your results using p-value.
