Answer
a) $1.81$ standard deviation below the mean.
b) A steer weighing $1000$ pounds because it is further away from the mean.
Work Step by Step
a)
$z=\frac{y-\mu}{\rho}=\frac{1000-1152}{84}=-1.81$
A steer weighing $1000$ pounds would be $1.81$ standard deviation below the mean.
b)
$z=\frac{y-\mu}{\rho}=\frac{1250-1152}{84}=1.17$
The answer is a steer weighing $1000$ pounds because it is further away from the mean.
