Researchers are testing a treatment for tumors. They've found that tumors are shrinking in patients receiving the new treatment. Their calculations
suggest that if chance were the only factor, there's a 9% chance they'd get
the same results. At a .01 significance level, do the researchers have proof
the new treatment is working?
A. No. They may have one piece of evidence, but they don't have
proof.
B. Can't be determined.
C. Yes. The significance level is low enough to be proof.
D. No. The P-value isn't low enough.
E. Yes. The Pvalue is lower than the significance level.
