Final answer:
After calculating the conversion rates for both sales pages, it's clear that both pages have the same conversion rate of 5%, which means the correct choice is c) Both have the same conversion rate.
Step-by-step explanation:
To determine which sales page has the better conversion rate, we need to calculate the ratio of sales to visitors for each page. For Sales Page #1, the conversion rate is 50 sales per 1,000 visitors, which is a 5% conversion rate (50/1,000 x 100). For Sales Page #2, the conversion rate is 80 sales per 2,000 visitors, which is also a 4% conversion rate (80/2,000 x 100). Therefore, the answer is c) Both have the same conversion rate, as both pages have a conversion rate of 5%.
