The two-tailed P value is 0,0431 (About 1 probability on 23)
By conventional criteria, this difference is considered to be
statistically significant at 5% level.

Pleft= 0,9802     Pright= 0,0228
The P value answers this question: If the theory that generated the expected values were correct, what is the probability of observing such a large discrepancy (or larger) between observed and expected values? A small P value is evidence that the data are not sampled from the distribution you expected.
