Answer:
Step-by-step explanation:
The given data is represented in the attachment.
a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.
Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).
b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.
Thus,
P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5
