Question

when a new drug is created, the pharmaceutical company must subject it to testing before receiving the necessary permission from the food and drug administration (fda) to market the drug. suppose the null hypothesis is \the drug is unsafe.\ what is the type ii error?
o a. to conclude the drug is safe when in, fact, it is unsafe.
o b. not to conclude the drug is safe when, in fact, it is safe.
o c. to conclude the drug is safe when, in fact, it is safe.
o d. not to conclude the drug is unsafe when, in fact, it is unsafe.

Explanation:

A Type II Error occurs when we fail to reject a null hypothesis that is actually false. Here, the null hypothesis is "the drug is unsafe". So, a Type II Error would be not concluding the drug is safe (i.e., not rejecting the null hypothesis) when in fact it is safe (the null hypothesis is false).

Answer:

B. Not to conclude the drug is safe when, in fact, it is safe.
