The sample is biased because **people who shop in bookstores are likely to read more books than those who do not**. This means that the surveyed group is not representative of the entire population of shoppers at the mall, as those exiting a bookstore are already inclined towards reading, which could lead to an overestimation of the percentage of all mall shoppers who enjoy reading books.
