Apolygraph (lie detector) is an instrument used to determine if the individual is telling the truth. these tests are considered to be 95% reliable. in other words, if an individual lies, there is a 0.95 probability that the test will detect a lie. let there also be a 0.005 probability that the test erroneously detects a lie even when the individual is actually telling the truth. consider the null hypothesis, "the individual is telling the truth," to answer the following questions. a. what is the probability of type i error? b. what is the probability of type ii error? c. discuss the consequences of type i and type ii errors. d. what is wrong with the statement, "i can prove that the individual is telling the truth on the basis of the polygraph result."

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
