An agricultural field station is investigating the differences between the mean

Question

An agricultural field station is investigating the differences between the
mean yields of two varieties of corn. They are particularly interested
in testing if the second variety gives a lower yield than the first variety.
Because of fertility differences, both varieties were planted in each of seven farms across the State of Florida. At harvest time, the plots were harvested and the yield recorded. Suppose that the p-value had been .0093. This would mean: (a) There is strong evidence against the null hypothesis of equal mean

yields.

(b) There is no evidence to believe that the two varieties have a different mean yield.

(c) There is strong evidence to believe that the two varieties have the same mean yield.

(d) There is no evidence to believe that the two varieties do not have a difference in their mean yields.

(e) There is sufficient evidence to believe that the two varieties are paired on each farm

Explanation / Answer

Ans

A

P value less than 0.05 indicates that null hypothesis is rejected.

Here p value is 0.0093.

It means there is stromg evidence against the the null hypothesis of equal mean yields.
