You select a random sample of 150 people at a medical convention attended by 1 comma 755 people. within your sample, you find that 75 people have traveled from abroad. based on this sample statistic, estimate how many people at the convention traveled from abroad. would you be more confident of your estimate if you sampled 300 people?

Step-by-step explanation:

Hey there!

The equation of line which passes through the point (1,2) is (y-2) = m1(x-1)(i)

The another given equation is y= 2x + 3(ii)

Comparing the equation (ii) with y= mx+c we get;

Slope (m2)= 2.

As per the condition of perpendicular lines, m1*m2 = -1.

m1*2 = -1

Therefore, m1 = -1/2.

Keeping the value of m1 in equation (i) we get;

(y-2) = -1/2(x-1)

y - 2 = -1/2x +1/2

y = -1/2 X + 1/2 + 2

Therefore, the required equation is y = -1/2 X + 5/2.

Hope it helps!
