Expert Solution
Step 1
For part a) of the question,
It is clearly mentioned in the question that the agricultural researcher wants to know whether the mean number of plants for each type of plots are equal or not .
So, clearly option B) will be the correct option
i.e. Ho: usludge =uspring=uno till and H1: atleast one of the means is different
