Answer

Brief Explanations:

The question asks for the interpretation of the proportion of starting - salaries within the range of $30,000 to $70,000 for a normal distribution with mean $\mu = 49000$ and standard deviation $\sigma=9000$. The proportion within the range is found by calculating the z - scores and the area between them. A high proportion within the range means most graduates' starting salaries fall in this interval.

Answer:

The proportion of starting salaries within a range of $30,000 to $70,000, from a normal distribution with $\mu = 49000$ ($\sigma = 9000$), is $p = 0.9727$.
