Normality of errors
-----------------------------------------------------------------
                         Method Statistic  p.value
 Shapiro-Wilk normality test(W) 0.9475889 0.187264

As the calculated p-value is greater than the 5% significance level, hypothesis H0 is not rejected. Therefore, errors can be considered normal

-----------------------------------------------------------------
Homogeneity of Variances
-----------------------------------------------------------------
                              Method Statistic p.value
 Bartlett test(Bartlett's K-squared)  4.036888 0.85378

As the calculated p-value is greater than the 5% significance level, hypothesis H0 is not rejected. Therefore, the variances can be considered homogeneous

-----------------------------------------------------------------
Independence from errors
-----------------------------------------------------------------
                 Method Statistic   p.value
 Durbin-Watson test(DW)  2.324604 0.2484349

As the calculated p-value is greater than the 5% significance level, hypothesis H0 is not rejected. Therefore, errors can be considered independent

As the calculated p-value, it is less than the 5% significance level. The hypothesis H0 of equality of means is rejected. Therefore, at least two treatments differ
