Question

agree or disagree

A type II error is when one fails to reject something. A type II error is when the nully hypothesis is accepted to be true even when the nully hypothesis is actually false. So, the drug itself is, in fact, safe but we all determined it to be unsafe. So, therefore, it is the error.

So in this case, the answer would be B. The drug is actually safe but most people would view this type of situation as a "false positive." When pharmacists go to make all these different drugs and medicine, they double check their steps to make sure everything is good with the medicine itself. Pharmacists are pretty good at having the right technology to help get the best results. For example, a Pharmacist is not going to put an unsafe drug on the shelf because that would look bad for the business and hurt them financially. So, they always double check to make sure everything is good before just handing it out to people.

Answer 1

Disagree with the part "So, the drug itself is, in fact, safe but we all determined it to be unsafe."

In case of testing a drug, the null hypothesis would be the drug is safe and the type of II error will be "the drug itself, in fact, not safe, but we all determined it to be safe". As you mentioned "A type II error is when the nully hypothesis is accepted to be true even when the nully hypothesis is actually false"

You might think that it is the opposite of "So, the drug itself is, in fact, safe but we all determined it to be unsafe." but it is not because the null hypothesis would not be "the drug is unsafe".

I hope you understand the concept, if you have any doubts then please let me know.
