An article reported that 73% of companies have Twitter accounts. An economist thinks the percentage is higher at technology companies. She samples 70 technology companies and finds that 55 of them have Twitter accounts. Can she conclude that more than 73% of technology companies have Twitter accounts? Use the 0.05 level of significance with the p-value method and Excel.
