An irrational number is a number that cannot be expressed as a quotient of two integers. Note that $7 = \frac{14}{2}$. 14 and 2 are integers. Thus, $7$ is a rational number. $\in$ means the number is an element of the given set. Since $7$ is a rational number, it is not an irrational number. Therefore, the given statement is false.
