A Survey of 40 Students at a Local College Asks

A survey of 40 students at a local college asks, "Where do you buy the majority of your books?" The responses fell into three categories: "at the campus bookstore," "on the Internet," and "other." The results follow. Use Excel to estimate the proportion of the college students who buy their books on the Internet. $\begin{array} { l|l|l|l|l|l| } \text {bookstore }&\text {bookstore }&\text { Internet}&\text { other }&\text { Internet}&\text { other }&\text {bookstore }\\\text { other} & \text { bookstore } & \text { bookstore } & \text { bookstore } & \text {bookstore } & \text {bookstore } & \text { other } \\\text { bookstore } & \text { bookstore } & \text { bookstore } & \text { Internet } & \text { Internet } & \text { other } & \text { other }\\\text { other } & \text { other } & \text { other } & \text { other } & \text { other } & \text { Internet } & \text { bookstore }\\\text { other }& \text { other } & \text { Internet} & \text { lother} & \text { bookstore } & \text {bookstore } & \text {other }\\\text { bookstore } & \text { Internet } & \text { Internet } & \text {other } & \text { bookstore }\\\end{array}$
