A random sample of 35 executives from companies with assets over $1 million was selected and asked for their annual income and level of education. The ANOVA comparing the average income among three levels of education rejected the null hypothesis. The Mean Square Error (MSE) was 243.7. The following table summarized the results:
|
High School or Less |
Undergraduate Degree |
Master's Degree or More |
|
| Number sampled | 7 | 12 | 16 |
| Mean salary (1,000's) | 49 | 80.0 | 82.0 |
When comparing the difference in mean annual incomes for
executives with Undergraduate and Master's Degree or more, the
following 95% confidence interval can be constructed:

1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
