Analysis
One can observe that the placement of the boxplots are gradually moving down the y axis as the SES value increases, with the the box plot in the fifth socioeconomic level displaying the lowest median. Thus, we can predict that an increase in an individual’s socioeconomic level leads to a decreased risk of developing Alzheimer’s.

The overall p-value of 0.005927 is less than the significance level of 0.05, thus representing that there is a relationship between the individual’s socioeconomic level and their MMSE scores.
In regards to the specific levels of SES, the estimated coefficient of 0.4657 in SES 2 and a p-value of 0.3810 portrays that there is an increase in the MMSE score from the reference level of 27.6023 while there may not be a significant relationship between SES 2 and the MMSE score.
The estimated coefficient of SES 3 is -0.0291 while the p-value is 0.9587, thus signifiying that there is a decrease in the MMSE score in relative to the reference level, although there is no significant relationship since the p-value is less than the significance level.
The estimated coefficient of SES 4 is -1,2239, thus signifying that there is a decrease in the MMSE score by 1.2239 in relative to the reference level of 27.6023. The p-value of SES 4 is 0.0346, meaning that there is a relationship between SES 4 and the MMSE scores.
Finally, the estimated coefficient of SES 5 is -3.3166, meaning that there is a decrease in the MMSE score by 3.3166 from the reference level of 27.6023. The p-value of SES 5 is 0.0215, signifying that there is a relationship between SES 5 and its MMSE score.
