##  Shapiro-Wilk normality test
## 
## data:  res_aov$residuals
## W = 0.93803, p-value = 0.2681

The distribution of the data is normally distributed.

Equality of Variances Test

There is quality of variances among the levels of Dosage.

#One-way ANOVA

##             Df Sum Sq Mean Sq F value Pr(>F)
## Dosage       5 0.5189  0.1038   0.844  0.544
## Residuals   12 1.4759  0.1230

Result: There is no significant differnce among the different Dosages.

No pairwise comparison since the result above is not significant
