Consider the sample data for plants A, B, C & D of the above company, which are
tabulated in table 1. Test whether the four means are equal at the 5% level of significance. Perform a test that will compare all 4 means at once. We are not interested in pair-wise comparisons at this stage. Please show all the steps in your calculations.
Table 1:
A B C D
333 328 320 333
332 329 321 321

Check: One-way analysis of variance

use one-way analysis of variance if the test variable i.e. the scores ( the dependent variable ) follows a normal distribution in each level of your Independent Categorical Variable which is Plants , otherwise, use a kruskal Wallis Test. I would suggest you use Kruskal Walli because the sample size for each level is not large enough and may show skewness.

Could you please send the answer to me.

Hello,
