Problem 8. A parking lot contains 100 cars that all look quite nice from the outside. However, k of these cars happen to be lemons. The integer k is known to lie in the range 0,1,2, with all values equally likely. (a) We testdrive 20 cars chosen at random without replacement, and to our pleasant surprise, none of them turn out to be a lemon. Given this knowledge, what is the probability that k0 (b) Repeat part (a) when the...
(10 points) A lot of 100 items contains k defective items. M (Ms100) items are chosen at random and tested (a) (2 pts) How many different ways can we choose M items from 100 items in the lot? (b) (4 pts) How many different ways that among the M items chosen, m (msk) are found 1. defective? the M items chosen? probability that the lot is accepted? (c) (2 pts) Based on (a) and (b), what is the probability that...
A lot of 100 cars contains 10 defective cars and 90 nondefective cars. If I randomly select 2 cars from the lot, what is the probability that both will be nondefective?
A lot of 100 items contains k defective items. m items are chosen at random and tested. What is the probability that r items are found defective
9) Several cars parked in a large parking lot sustain hail damage during a storm. The repair costs for the cars are uniformly distributed between $100 and $600. A car is selected at random from the lot. Find the probability that the repair costs for the car are less than $405. Provide an exact answer.
Letr denote the مقع O time it takes to find parking spot. Suppose we take random sample of n = 666 cars entering the parking lot between 9am and lou.m. and record the time it takes for them to find parking spot. For For our sample, x=8 and s-4. Find 90% confidence interval for r. Kapacitet Find the right endpoint of the interval, and round the answer to two digits past the decimal.
the Let M denote mean time it takes to find a parking spot for cars entering particular parking lot at Texas Road House between 9 and 10a.m. Suppose we make the assumption that the underlying distribution of all such parking times is not too skewed estimate that we will get sample standard deviation s= 7.5. If wish construct 997. confidence interval for r with width than 2, what is the minimum sample size could take ? and we
A batch of n = 60 items contains m = 15 defective items. Suppose k = 10 items are selected at random and tested. What is the probability that we find exactly five defective items?
A batch of n = 50 items contains m = 10 defective items. Suppose k = 10 items are selected at random and tested. How many items, k, do we need to sample, in order to get at least one defective item, with probability greater than 0.5?
CLUSTER SAMPLING WITH ESTIMATION Suppose a population of size N is divided into K- N/M groups of size M. We select a sample of size n -km the following way: » First we select k groups out of K groups by simple random sampling . We then select m units in each group selected on the first step by simple random sampling . The estimate of the population mean is the average Y of the sample. Let μί be the...
