Question

What proportion of population values are greater than or equal to 2? a. 0 b. 1/6 c. 2/6 d. 5/6 e. 1 What is the probability of getting a value of sigma = 6 in a draw from this population? a. 2/6 b. 3/6 c. 5/6 d. 4/6 e. 0 Each computer chip on a production line is either Detective or Not-defective. The probability of a chip being. Determine is constant independent of others. Which random variable represents the number of Defective chips in a random sample of fixed size from this production line? a. Geometric random variable b. Binomial random variable c. Negative Binomial random variable d. Hypergeometric random variable e. Poisson random variable 1000 dealers provide a particular machine part. Half of the dealers carry both 2017 and 2016 catalog items in stock and the other half carry only 2016 catalog items in stock. Which random variable represents the number of dealers that carry both 2017 and 2016 catalog items in a random sample of 100 dealers, sampled without replacement? a. Bernoulli random variable b. Binomial random variable c. Negative Binomial random variable d. Hypergeometric random variable e. Poisson random variable A car passes an airbag safety test if its airbag inflates in less than t seconds. The probability of a car having an airbag that inflates in less than t seconds is 0.8 independent of other cars. What is the probability of observing 5 cars falling this airbag safety test before the first car passes the test?

Explanation / Answer

7)

B) binomial random variable is correct

,as the probability of defective is p .

teh number of sample = n

P(X = k) = n Ck * p^k * (1-p)^(n-k)
