Consider the following scenario to answer the questions that follow.
Suppose a large electronics retailer has 1,000 salespeople who sell new computers and new computer service plans. The retailer is interested in increasing the percentage of customers who purchase a computer service plan (or warranty) with their new computers. The retailer decides to test two sales pitches by splitting its salespeople into two groups of 500 and giving each group a slightly different sales pitch to recite to customers prior to the consummation of a computer sale.
The first group of salespeople recites the following sales pitch: "Before you pay, I wanted to let you know that all of our new computers come automatically with a warranty that adds $150 to the purchase price. If you wish to opt out and decline the warranty, all you need to do is fill out and sign a form attesting to your refusal."
The second group of salespeople recites the following sales pitch: "Before you pay, I wanted to let you know that, although none of our new computers come automatically with a warranty, you can purchase one by adding $150 to the purchase price. If you wish to opt in and accept the warranty, all you need to do is fill out and sign a form attesting to your acceptance."
-Suppose that 84% of customers hearing the sales pitch from the first group purchased the warranty and that 19% of the customers hearing the sales pitch from the second group purchased the warranty.The managers concluded that ________ were likely present and changed company policy such that all salespeople are required to recite the sales pitch given by the first group.
