In order to test if there are real difference between these 3 programming languages, an experiment is carried out using 15 sample programs. Then the three programming languages assigned at random to the sample programs. The execution time in seconds is recorded as follows. Complete the ANOVA table below and conclude whether there is enough evidence to say that there is a significant difference between the programming languages at 5% significant level.
