Question

A randomized experiment was performed to determine whether two fertilizers set The results of the Which of the following experiment best. describes the conclusion .ha, can be drawn from, Um experiment there is no statistical evidence of difference in the yields between fertilizer A and fertilizer There is a borderline statistically significant difference in the yields between fertilizer A and fertilizer There is evidence of a statistically significant difference in the yields between fertilizer A and fertilizer There is evidence of a statistically significant difference in the yields between fertilizer A and fertilizer There is a statistically significant difference in .he yields between fertilizer A and fertilizer

Explanation / Answer

For independent groups,

SE(FAbar-FBbar)=sqrt (SF^2/nF)+SB^2/nb)=sqrt (3.68^2/16+4.93^2/17)=1.51

t=(FAbar-FBbar)-0/SE(FAbar-FBbar)=(19.54-23.39)-0/1.51=-2.55

The df=29, the test statistic falls between 0.01 and 0.05. Thus p value is less than 0.05, therefore, reject null hypothesis. There is statistically significant difference between yields of fertilizer A and B.
