A recent study evaluated how addicted teenagers become to nicotine once they start smoking. The response variable was the number of yes answers on a questionnaire called the Hooked on Nicotine Checklist (HONC). Of teenagers who had tried tobacco, the mean HONC score was 3.8 (s=4.4) for the 141 females and 2.4 (s=3.5) for the 178 males. Complete parts a through c below. ... a. Find the standard error comparing the sample means. Interpret. The standard error is se= (Round to four decimal places as needed.)
