Question:

Recall (from Exercise 2.26) that the mean base salary of a software engineering manager is $126,417 (Electronic Design’s 2012 Engineering Salary Survey). Assume the distribution of base salaries for all software engineers is mound-shaped with a variance of 225,000,000. Sketch the distribution, showing the intervals μ ± σ  s, μ ± 2σ and μ ± 3σ on the graph. Estimate the proportion of software engineering managers with base salaries in each interval.


Data from Exercise 2.26

According to Electronic Design’s 2012 Engineering Salary Survey, the mean base salary of a software engineering manager is $126,417—the highest mean among all types of engineers. In contrast, a manufacturing/ production engineer has a mean base salary of $92,360. Assume these values are accurate and represent population means. Determine whether the following statements are true or false.
