a. Suppose that 5 % of the items produced by a factory are defective. If 5 items are chosen at random, what is the probability that none of the items are defective? Write your answer as a decimal accurate to three decimal places. b. Suppose that 7.9 % of the items produced by a second factory are defective. If 5 items are chosen at random from the second factory, what is the probability that exactly one of the items is...

The probability that a part produced by a certain factory's assembly line will be defective is...

The probability that a part produced by a certain factory's assembly line will be defective is 0.036. Find the probabilities that in a run of 44 items, the following results are obtained. (a) Exactly 3 defective items (b) No defective items (c) At least 1 defective item (Round to four decimal places as needed.)

The number of defective items produced by a machine (Y) is known to be linearly related...

The number of defective items produced by a machine (Y) is known to be linearly related to the speed setting of the machine (X). Data is provided below. a) (3) Fit a linear regression function by ordinary least squares; obtain the residuals and plot the residuals against X. What does the residual plot suggest? b) (3) Plot the absolute value of the residuals and the squared residuals vs. X. Which plot has a better line? c) (4) Perform a weighted...

11.7. Machine speed. The number of defective items produced by a machine (Y) is known to be linearly related to the speed setting of the machine (X). The data below were collected from recent quality control records. #d. Estimate the variance function by regressing the squared residuals against-X, and then calculate the estimated weight for each case using (11.16b). #e. Using the estimated weights, obtain the weighted least squares estimates of f30 and th. Are the weighted least squares estimates...

5) A lumber grading system is known to be defective 20% of the time. When the machine works properly, 20% of the lumber that passes through is rejected, but 50% of the pieces are rejected when it is defective,. In either case, pieces that are accepted are graded this way: 20% #1 Grade 70% #2 Grade 10% #3 Grade a. Draw a tree diagram outlining each possible outcome. Include all of the relevant probabilities as well as the probability for...

The mean diameter of a ball bearing produced by a certain manufacturer is 0.80 cm with...

The mean diameter of a ball bearing produced by a certain manufacturer is 0.80 cm with a standard deviation of 0.03 cm. A sample of 36 ball bearings is randomly selected from a production run. Suppose the diameter is normally distributed. c. What is the probability that a randomly selected ball bearing will have a diameter of less than 0.798 cm? c. What is the probability that a randomly selected ball bearing will have a diameter of less than 0.798...

The breaking strengths of cables produced by a certain manufacturer have a mean, μ , of...

The breaking strengths of cables produced by a certain manufacturer have a mean, μ , of 1900 pounds, and a standard deviation of 100 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 21 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1959 pounds. Assume that the population is normally distributed. Can we support, at the 0.1 level of...

2a. When a new machine is functioning properly, only 5% of the items produced are defective. Assume that we will randomly select two parts produced on the machine and that we are interested in the number of defective parts found. Compute the probabilities associated with finding exactly one defect. 2b.When a new machine is functioning properly, only 5% of the items produced are defective. Assume that we will randomly select two parts produced on the machine and that we are...
