Conclusion

We can reject the null hypothesis at any reasonable level of significance because our p-value is zero.  Therefore we have suffient evidence to say the average time someone changes their college major is not 3.  Based on this data that we found, we can say that the average number of times North Olmsted High School faculty members changed their college majors is not three.  Because our study included teachers, who generally know what they'd like to be upon entering college, it is not surprising to us that the results show with significant evidence that the average number of changes in college major is not three.
