Passage:
A subscription software company claims that offering customers a “one month free” trial will increase long term revenue. The company points to a pilot in which the average revenue per new customer over the next six months was higher for customers who received a free trial than for customers who did not. The company concludes that the free trial causes customers to value the product more and therefore spend more afterward.
Which of the following, if true, most strengthens the company’s conclusion?
Select one option.
