Are Hormones Making Us Shorter?

Conclusion (The End)

We failed to reject the null hypothesis at the 0.05 level of significance, since p-value was greater than alpha.  Therefore, there is not significant evidence to say that people are now shorter than 58 to 60 years ago.

It appears from this study that people are now getting taller.  However, there may be bias in our study due to the fact that our random sample consisted of many tall students.
