A specific type of medical device, once manufactured, is tested and 3% of the devices are found to have defective parts. Let X = the number of medical devices with defective parts in a random sample of size n = 20.
-
(i) Determine the probability that 2 or more of the devices are defective.
-
(ii) Determine the probability that between 1 and 4 (inclusive) devices are defective.

Problem 6. A device is tested. If it is found to be defective, then two more devices from the same lot are tested. However, if the first device is found to be okay, then only one additional item is tested. Assume that the devices are independent and that they come from, a batch in which 10% are defective. LetX denote the random variable that gives the total number of defective devices encountered during this testing procedure. (a) Draw a tree...

A noted psychic was tested for Extrasensory Perception (ESP). The psychic was presented with a series of face-down cards and was asked to identify the correct symbol on each card (out of five possible choices). Let pp be the probability that the psychic will correctly identify the symbol on any given card. If the psychic truly has ESP, then she should be correct more than 20% of the time, meaning p>0.20p>0.20. This hypothesis was tested using a significance level of...

Question 2: A company generally purchases large lots of a certain type of laptop computers. A method is used that rejects a lot if more than 2 defective laptops are found in a lot. Past experience shows that 10% laptops are defective. What is the probability of rejecting a lot of 20 units? What is the probability that in a batch of 20 laptops between 3 and 5 (inclusive) laptops are defective? On the average how many defective laptops are...

Consider the population of all 1-gallon cans of dusty rose paint manufactured by a particular paint company. Suppose that a normal distribution with mean μ = 6 ml and standard deviation σ = 0.2 ml is a reasonable model for the distribution of the variable x = amount of red dye in the paint mixture. Use the normal distribution model to calculate the following probabilities. (Round your answers to four decimal places.) (b) P(x < 6.2)= (d) P(5.6 < x...
