 <p><strong>Bonus / Extra practice</strong>: Let’s say you change your survey so participants can rank their response 1-10 (inclusive). Create a randomly sampled vector of 30 survey responses. (hint use <code>seq()</code> and <code>sample()</code> and set the replace argument to <code>TRUE</code>). Store the output as <code>my_responses_2</code>. Examine the data by typing the name in the Console using a function.</p>
