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.

Access to Internet State Yes No Alaska 48 12 California 87 3 Virginia 44 6 New Mexico 60 10

a. Using a = 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 PHStat.
