A veterinarian wants to estimate the difference between the average weight of male and female bull terriers. A random sample of $35$ male bull terriers had an average weight of $58.34\text{ pounds}$ with a standard error of $4.69\text{ pounds}$. A random sample of $35$ female bull terriers had an average weight of $52.63\text{ pounds}$ with a standard error of $4.02\text{ pounds}$.

What is the standard error of the difference(male-female) between the sample means?

A

$\sqrt { \dfrac { { (4.69) }^{ 2 }-{ (4.02) }^{ 2 } }{ 70 } } $

B

$\sqrt { \dfrac { { (4.69) }^{ 2 }+{ (4.02) }^{ 2 } }{ 70 } } $

C

$\sqrt { \dfrac { (4.69)-(4.02) }{ 35 } }$

D

$\sqrt { \dfrac { { (4.69) }^{ 2 }-{ (4.02) }^{ 2 } }{ 35 } } $

E

$\sqrt { \dfrac { { (4.69) }^{ 2 }+{ (4.02) }^{ 2 } }{ 35 } } $
