Assume that the conditions for correlation are met. Is the following statement true or false? If it is false, explain. A correlation of 0.89 indicates a strong, position association.
Compute sst, ssa, ssb and ssab. Set up an ANOVA table and test for any significant main effect and any interaction effect. Use a = .05.
Construct a 95% confidence interval and determine whether the modified (after) layout has increased average worker productivity. Assume that the differences between hourly production outputs are normally distributed.
What is the final task after completing the analysis of significant results? Why is the size effect useful at this stage?
A sample of size 21 is taken and a significance test for H0 : u = 0 versus Ha : u doesnt equal 0 is run. The test statistic is t = 1.71. Use 3 decimal places for t values and 2 decimal places for p-values. What are the degrees of freedom for this
Foofy obtained a significant Fobt from an experiment with five levels. She therefore concludes that changing every condition of the independent variable results in a significant change in the dependent variable. (a) Is she correct? Why or why not?
If a particular shipment of thousands of components actually has a 8% rate of defects, what is the probability that this whole shipment will be accepted? Round to three decimal places.
Good machines are expected to produce no more than 1% defective products. After he evaluates 540 shoelaces, and finds that 17 are defective. If Dilbert has to report a confidence interval with a margin of error equal to 1.5%, how many shoelaces sho
At the .025 level, has Holdlonger increased the shelf life of the chlorine? Estimate the p-value. State the null hypothesis and the alternate hypothesis. State the decision rule for .025 significance level. Compute the value of the test statistic.
