Answer #1
Source SS df MS F
Factor A 76 2 38 9.19
Persons 690.643 5 138.129
Error (within) 41.333 10 4.133
Total 807.98 17

p value = 0.005

p value < 0.05

so,  there is a statistically significant difference between the means of caffeine consumption

......

η2 = 76 / 807.98

=0.094

................

for tukey test, not complete information

.................
