$\bar{x} = 49$

$10\bar{x} = 490$

$6\bar{x}_w + 4\bar{x}_m = 490$

$6(51) + 4\bar{x}_m = 490$

$\bar{x}_m = 46$

3. The mean for all 10 people is 49,
hence the sum of the parameter for all is 490.
The sum for the women is 6(51) = 306.
The sum for the men is 490-306.
Can you find the men's mean from here?

uh-oh, I was beaten on the draw!
