<u>Woodson high school </u> | 110 | 120 | 80 | 310 |
<u>Valley high school </u> | 180 | 150 | 120 | 450 |
<u>Riverside high school </u> | 160 | 140 | 200 | 500 |
<u>Total </u> | 450 | 410 | 400 | 1260 |
Question: In decimal form, to the nearest tenth, what is the probability that a randomly selected riverside high school student is in twelfth grade?
First, find 12-grade and riverside high school number. 200. Take the total lined up with total number, which is 1260, and divide 200 divided by 1260.
200/1260=0.2

Answer:
(c) A false negative (concluding the job candidate is not a drug user when he or she indeed is)
Step-by-step explanation:
First, we need to determine if it is possible for type II error to occur or not.
In analysis, type 2 error occurs when the stated null hypothesis is false.
The given null hypothesis here is "a job candidate is not a drug user" which indicates false. This means that option (e) cannot be the solution.
Having established that there is a possibility for an occurrence of type II error.
Next, is to determine the error.
Type II error implies false negative; hence, options (a), (b) and (d) cannot be the solution.
(c) is correct.
