Determining the p-value of two random group

Reference no: EM13110110

A study was carried out and subjects were randomized to 2 groups:

Group A: control diet group, N=154

Group B: a fruit-and-vegetable group, N=154.

The 97.5% CI for mean changes in Group B minus mean change in Group A is (-4.7 to -0.9). Suppose we want to compute a two-sided p-value to compare the two groups. Without doing any further calculation, which statements must be false? (Note: The actual p-value may differ from all these values).

A) 0.01
B) 0.04
C) 0.02
D) 0.001

Please explain the reasoning behind the answer.
