Question 888972
In the experiment in Example 4, we got a P-value = 0.000 for testing H0: p = 1/7 about dogs’ ability to diagnose urine from bladder cancer patients.
 a. For the significance level 0.05, what decision would you make?
Ans: Since the p-value is less than 5%, rejec Ho.
-------------------------------------------------------- 
b. If you made an error in part a, what type of error was it?
Ans: You rejected Ho. That is a Type I error.
----------------------------------------------------
 Explain what the error means in context of the Dr. Dog experiment.
You rejected the Ho-hypothesis that the dogs abiltiy was random.
If your rejection is an error, you failed to realize that the dog's
dianosis ability is random.
Cheers,
Stan H.
