1. Kane discusses the concentricity of an engine oil seal groove. Historically, the standard deviation for the concentricity is 0.7. The target average concentricity is 5.6. To monitor this process, he periodically takes a random sample of three measurements
a. A recent sample yielded a sample mean of 5.8. Conduct a hypothesis test to determine whether the true mean concentricity has changed. Use a 0.05 significance level.
b. Find the p-value associated with the test in part a
c. Construct a 95% confidence interval for this situation. Use this interval to determine whether the true mean concentricity has changed. Discuss the relationship of the 95% confidence interval and the corresponding hypothesis test.
d. What did you assume to do these analyses? How can you check these assumptions?
List all samples of size 2, and compute the mean of each sample. Compute the mean of the distribution of sample means and the population mean. Compare the two values. Compare the dispersion in the population with that of the sample means.
Use confidence intervals to determine whether or not (a) we can be 95% certain that the average woman considers herself overweight as compared to her ideal weight.
Treatment conditions and obtains 30 scores in each treatment. If the researcher used a repeated-measures design, then how many individuals participated in the research study?
Determine the values of the slack and surplus variables and interpret them. Which constraints are binding constraints? Describe.
It is very difficult for small businesses to be successful. The Small business administration estimates that 20 percent will dissolve or go bankrupt within two years. A sample of 50 new businesses is selected. (show work) (a) What is the mean and ..

The manufacture of a new compact car claims the miles per gallon (mpg) for the gasoline consumption follow a normal distribution with mean of 25.9 mpg and standard deviation of 9.5 mpg . if 36 such cars are tested , what is the probability the ave..
Does thus data support the researchers' hypothesis? Test the relevant hypothesis using a = .1 by first calculating a p-value.
State the null and alternate hypotheses if you want to determine whether the mean amount spent is higher for men than for women,
What are the main differences between descriptive and inferential statistics? Give examples of each. When would random sampling not be the best approach to sample selection? Give an example.
