This study uses a quantitative approach to evaluate the trustworthiness of e-businesses as measured by the E-business Trustworthy Index, EBTI, developed as part of this research. The problem is that despite the importance of e-business trustworthiness and the findings from many studies, there are few if any objective measures that evaluate the trustworthiness of online retail stores. The development of the EBTI benefits both e-businesses and online shoppers. This study has two purposes. A model of trustworthiness or an e-business trustworthy index, EBTI, was synthesized from research and used with a quantitative approach to examine the state of e-business trustworthiness. In doing so, the question concerning if e-businesses are trustworthy is explored. The EBTI will be used by raters to evaluate a sample of e-businesses. The same e-businesses will be evaluated by consumers. The data derived from the EBTI and the consumer survey will be analyzed.
