Question 17 Not yet The probability of a randomly selected person is suffering from a certain disease DIS is 0.001. The test to detect DIS has a correct detection rate of one that is, for a person with DIS, the test will always detect the disease. But for a person without DIS, the test has probability 0.005 to give false detection of the disease. Given that a person tests positive for DIS, what is the probability that person actually has it? Choose the closest value from the following: answered Marked out of 3.00 O 1/5 Flag question O 1/1000 O 1/6 1/200
Question 18 Please choose the statement that is false about random number generation: Not yet answered Marked out of 3.00 The inverse transformation method can be used to sample data from both continuous and discrete probability distributions For a linear congruent generator that has a prime number m as the divisor for the modulus, the obtained random numbers have a maximum period of (m-1) In random number generation using linear congruent generator, we don't need to worry about cycles. Uniformly distributed random numbers can be generated using a linear congruent generator P Flag question
Question 19 Not yet Let X1, X2, ...,X100 be 100 independent observations from a distribution X which is not normally distributed. Suppose it is known that the mean of this distribution X is 26 and the standard deviation is 6. What can we say about the sample mean x? answered O a. None of the other answers Marked out of 3.00 Ob. x has an approximately normal distribution with mean=26 and standard deviation=6 Flag question Oc. i cannot be approximated with a normal distribution since X is not normal O d. X = 2.6 Oe. x has an approximately normal distribution with mean=26 and standard deviation=0.6
