1. When a researcher has two samples with two means, one of the assumptions for two samples is independence of between the two samples. What does this mean? What happens if the independence assumption is violated?
2. What are the differences among a proportion, a percentage, and a ratio? When would a researcher use a hypothesis test for the difference in two population proportions? Explain.
The mean of a standard normal probability distribution.
A mean score on a standardized test is 50 with a standard deviation of 10. Answer the following
The ANOVA table is given below,as well as a table of means and standard deviations for the three groups. Evaluate the t statistic for testing contrast
Suppose that you're the Quality Manager for the Emerson D. Meritz Machine Tool Company. Your model IE566 grinding machine is afflicted by three types of defects classified as major (type A), serious (type B) and minor (type C).
Find the probability of accepting a lot as a function of the actual fraction of defective chips. In particular, let the actual fraction of defective chips in a given lot equal any of 0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.14, 0.16, 0.18. Then compu..
In addition, record the values for the UCL, center line, and LCL. Also, record any points that are out of control. Use a z-value of three.
