Sometimes the extent to which two groups differ is quite obvious. For example, if one group of individuals has a mean of 20 speeding tickets, while another group has a mean of 2, we can be pretty sure that the difference is statistically significant. But sometimes it is less clear. What if one group had a mean of 10, while the other had a mean of 7? T-tests provide a way to determine if differences between means are enough to be statistically significant. 
Freshmen and SeniorsFor this assignment, you will conduct a two-sample t-test to determine if college freshmen and seniors have a significantly different number of speeding tickets. Using the data provided below, conduct a two-sample t-test.

Present the result of the two-sample t-test.
Explain whether or not the result is statistically significant.
Discuss what this implies for freshmen and seniors, and whether or not the results fit with your own expectations.
Be sure to include supporting detail from the readings, as well as other scholarly sources.
