- Spacers are manufactured to the mean dimension and tolerance shown in Figure 29-12. An inspector measures 10 spacers and records the following thicknesses: 0.372" 0.376" 0.379" 0.375" 0.370" 0.373" 0.377" 0.378" 0.371" 0.380" Which spacers are defective (above the maximum limit or below the minimum limit)? All dimensions are in inches.Here is an ANOVA Table: Source SS d.f. MS F p-value Among groups 1000 4 Error 3000 56 Total How many groups were in the study? How many subjects were in the study? Complete the ANOVA table. What is the critical value at 0.01? What conclusion is appropriate?Find the margin of error for the given values of c, o, and n. c=0.90, o=2.2, n =64 Use the table of common critical values:
- A contingency table has 6 rows and 3 columns. A. How many degrees of freedom are there? B. What is the critical value if α = 0.05? C. Suppose the test value was 17.500. What is the p-value, reported to 4 decimal places?Find the margin of error for the given values of c, σ, and n. c=0.90, σ=3.2, n=49 Table of Common Critical Values Level of Confidence zc 90% 1.645 95% 1.96 99% 2.575 E=_____ (Round to three decimal places as needed.)A sample is counted for 10 minutes and results in 530 gross counts. A 30-minute background count results in 1,500 counts. The detector efficiency is 0.10 cpm/dpm.

The critical value for the ANOVA at .05 level is 7.815. Knowing nothing about the individual cases that comprise the ANOVA test, what advice to you give to the researcher?The personality trait of "Conscientiousness" (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. Does the z score for the sample mean lie in the critical region (beyond the critical boundary)?
