To determine

a.

To find:

The expected body temperature of the species if the body temperature (in degrees Celsius) of a particular species of bird is a continuous random variable with probability density function defined by, $f\left(x\right)=\frac{3}{19,696}\left(x^2+x\right)$ for $x$ in $\left[38,42\right]$.

To determine

b.

To find:

The probability of body temperature below the mean if the body temperature (in degrees Celsius) of a particular species of bird is a continuous random variable with probability density function defined by, $f\left(x\right)=\frac{3}{19,696}\left(x^2+x\right)$ for $x$ in $\left[38,42\right]$.
