Question

Video Assessment Questions 1. What possible errors can occur at Norchem Drug Testing? 2. Which type of error is of greater concern to Norchem Drug Testing? 3. Norchem Drug Testing tries to ensure that the probability of a false positive is near zero. What type of probability is this? In the context of hypothesis testing, what would we call this probability? 4. Give a scenario other than drug testing that is designed to keep the probability of making a Type I error small.

Answer 1

solation :- © Two errors are test result comes back possible at Norchem Drug Testing back Positive when it is not (a false positive) or a test result comes negative. when it is not (a false negative). The goal of Norchern's multi-stage testing process is to minimize the probability of an error in either direction. solution Norchem Drug than a Concern A false positive is of greater False negative to Testing for aney other drug testing compnay. because of its serious consequences. A False Positive drug test means that when they shouldn't (e.g.put in prision, under house arust, etc) A false positive leads to false testing againest an individual

. Probability solution This probobility is a conditional we can state it as the probability that the test will come back positive "given" that the true result is negative if we assume as the hall hypothesis that the individual is not using drugs then resecting this rejecting this when it is true results in a false Positive, and within the content of hypothesis type 'error is committed. In statistie, probability of making a type I error Knewn as d. seenario solution The most well known is that the sudicial system. Presmed innocent until proven equility penalizing someone who is annocent is of greater concern freeing someone who is quilty By using the reasonable doubt threshold the system is designed to minimized the chance that someone who is innocent is founded quitly then
