An ecologist who analyzes water samples tests the nullhypothesis that any contaminants in the water are belowdangerous concentrations. Because he uses a = 0.05, aset of samples from a small lake that produced a P-valueof 0.07 led him to conclude that the evidence did notpoint to unsafe water conditions. Which is true?A) There’s a 7% chance the lake’s water really is safe.B) There’s a 93% chance the lake’s water really is safe.C) There’s a 7% chance his sampling would have shownas much contamination as it did even if the lake’swater really is safe.D) If the lake’s water really is unsafe, there’s a 5%chance he wouldn’t notice.E) If he had taken more samples, he probably wouldhave rejected the null and concluded that the waterwas unsafe.
