My report is on the year 2016 totals of infants deaths and morality in each state in the US with non-hispanic and hispanic infants. 

I choose this data to research because i was curious to see what the death rate for infants was in that time, and even though i did the data for 2016, i wanted to compare 2016 to 2018, and see what the difference was. But from my results, I can see that the infant death total as an non-hispanic is much higher than an hispanic race. 

 

In the Scatter plot, we can see that it would be a positive correlation between the two different race.

In the Box plot, we can see that the number of non-hispanic infant deaths is much higher than hispanic infant deaths. Non-hispanic has 6 outliers and Hispanics have only one outlier.
