Answer:

A. Isosceles

Step-by-step explanation:

Since two angles are congruent, then the opposite sides are congruent. The two congruent angles measure 70 and 70.

70 + 70 = 140

180 - 140 = 40

The third angle measures 40. The third side is not congruent to the other two, so the triangle is isosceles but not equilateral.

Solution :

a). The point estimate of proportion of college graduates among women who work at home,

$\hat p =\frac{166}{506}$

= 0.3281

99.5% confidence interval

$=\left( \hat p \pm Z_{0.005/2} \sqrt{\frac{\hat p (1- \hat p)}{n}} \right)$

$=\left( 0.3281 \pm 2.81 \sqrt{\frac{0.3281 \times (1- 0.3281)}{506}} \right)$

$=(0.3281 \pm 0.0586)$

$=(0.2695, 0.3867)$
