Question:
Four different designs for a digital computer circuit are being studied to compare the amount of noise present. The following data have been obtained:
Circuit Design | Noise Observed | ||||
1 | 19 | 20 | 19 | 30 | 8 |
2 | 80 | 61 | 73 | 56 | 80 |
3 | 47 | 26 | 25 | 35 | 50 |
4 | 95 | 46 | 83 | 78 | 97 |
1. Is the same amount of noise present for all four designs?
2. Perform the appropriate statistical analysis using an ANOVA based on an exploratory analysis to verify all necessary assumptions.
3. Find a 95% confidence interval for each of the Circuit Designs and at least one difference in two specific circuit designs. Look carefully at these confidence intervals for implications related to your statement of conclusions.
4. Write a formal statistical summary of your findings.
