A study on nicotine dependence for teenage smokers obtained a random sample of seventh graders. Of those seventh graders in the study who had tried tobacco, the mean HONC score was 2.8 with a standard deviation of 3.62 for the 150 females and mean of 1.6 and standard deviation of 2.92 for the 182 males. Conduct a two-sided significance testing to compare if there is a significant difference between the HONC score of the two genders. Assume 95% confidence level

State hyphotesis:

Compute for the test statistic:

Draw the necessary normal curve. Include the critical values and the test statistic.

Make a conclusion. C} There is a signicant difference between the means of the two groups. C} There is no signicant difference between the means of the two groups
