The mean time to expose a single panel in a circuit-board plant is two minutes with a standard deviation of 1.5 minutes.
a. What is the natural coefficient of variation?b. If the times remain independent, what will be the mean and variance of a job of 60 panels? What will be the coef cient of variation of the job of 60?c. Now suppose times to failure on the expose machine are exponentially distributed with a mean of 60 hours and the repair time is also exponentially distributed with a mean of two hours. What are the effective mean and CV of the process time for a job of 60 panels?
Since purchasing the software the average delivery time over twenty delivery days was 8.6 hours. At the 0.05 level of significance, test whether the software package has reduced the average time it takes to complete deliveries.
What is the difference between statistical significance and practical significance? Can a hypothesis test result be statistically significant and yet practically useless.
Pattern that most accurately represents mean, median and mode is?
Calculate the value based on this information. A new screening test for Lyme disease is developed for use in the general population. The sensitivity (ability to identify infected persons) is 60% and specificity (ability to identify non- infected p..
Given 0.2, 0.4, and 0.4 are the probabilities for the sale of 100, 200, or 400 dozen roses, respectively, then the EOL for buying 200 dozen roses is?
What is your initial perception of this information? What are other ways, beyond looking at the p-value alone, you could use to try to interpret what this outcome of r(2398) = -.21 tells us about the relationship between length of time taking drug..
At the .05 significance level can we conclude that there is more variation in the processing time of the new machine?
Use critical values and the previously given sample information to test the hypotheses you set up in part α by setting α equal to .10, .05, .01, and .001. How much evidence is there that the manufacturer's claim is false?
For each of the following sampling scenarios, determine which test statistic is appropriate to use when making inference statements about the population mean.
A company has developed the new battery, but the average lifetime is unknown. In order to estimate the average, a sample of 150 batteries is tested and an average lifetime of this sample is found to be 250 hours.
What happens to the confidence interval and the power of the test at a particular point of interest
Test, at the significance level of 0.05, whether the mean bacteria count for the plant discharge exceeds that for the upstream location.
