Answer:

A. 2.5 standard deviations below the average salary.

Step-by-step explanation:

In a normally distributed sample, the z-score measure how many standard deviations a measure is above or below the mean.

If the zscore is positive, the measure is above the mean.

If it is negative, the measure is below the mean.

A quality control specialist calculated thez-score associated with his own salary and found it was minus2.50. What is his salary?

This means that his salary is 2.5 standard deviations below the mean, that is the average salary.

The correct answer is A.

Parameterize $C$ by

$\vec r(t)=(1-t)(0,0,0)+t(1,3,6)=(t,3t,6t)$

with $0\le t\le1$ . Then the line integral is

$\displaystyle\int_Cxyz\,\mathrm dS=\int_0^1x(t)y(t)z(t)\left\|\frac{\mathrm d\vec r}{\mathrm dt}\right\|\,\mathrm dt$

$=\displaystyle18\sqrt{91}\int_0^1t^3\,\mathrm dt=\boxed{\frac{9\sqrt{91}}2}$
