5. I found independent samples of Math, Humanities and Social Science majors at a large university and recorded their heart rates while taking a statistics exam. Each sample had five students. The individual results for each individual are listed below their major in the table below. Run an ANOVA test to see if there is a significant difference in heart rates among the different majors as they took the statistics exam.

Math major

Humanities major

Social Science major

Answer #1
Source SS df MS
Between-treatments 26.1333 2 13.0667 F = 0.21998
Within-treatments 712.8 12 59.4
Total 738.9333 14

The f-ratio value is 0.21998. The p-value is .805702. The result is not significant at p < .05.

thus we can conclude that there is no significant difference between the three groups (p>0.05)
