eShopNet, an online clothing retailer, is testing a new e-mail campaign by sending one version of the e-mail with the word "free" in the subject line (version A) to a group of 1500 customers and another version of the e-mail with the word "discount" in the subject line (version B) to a different group of 1500 customers. This type of test is called A/B testing or split testing. After tracking the responses to the two different versions of the e-mail advertisement, eShopNet finds that 90 responded to version A (with the word "free") and 129 responded to version B (with the word "discount"). Using α = .01, was the response rate to version B significantly higher than the response rate to version A?
