Could you tell me this is which way anova classification, and also solve it with steps, please provide the calculations. Thank You

In order to improve the effluent water treatment process by achieving the biological

oxygen demand $($BOD$)$ of effluent $($less than $17ppm),$ an experimenter suggested two$-$

treatment methods. Five BOD readings $($in ppm$)$ obtained for each of the test methods

after $3$ days and $6$ days of incubation of the effluent samples are recorded by the

experimenter, as shown in the following table. Perform an ANOVA at $5\%$ level of

significance by considering test methods and days of incubation are fixed.
