What if there were 2000 seeds and 1100 produced white-fruited plants & 900 yellow-fruited? Are these results statistically s

To explain this we need to say the following:
As explained above, white plants are Heterozygous and the out come is around 50/50. What this indicates is  that yellow fruited plants are most likely homozygous recessive to give you the almost 50/50 outcome. 
The following Chi-square can demonstrate that
<span>                                    ---------------White </span>
<span>                                    ---------------W w </span>
<span>                                    Yellow w Ww ww </span>
<span>                                    ---------- w Ww ww </span>
