You randomly selected 50 individuals twice. In the first sample, 15 of the 50 had blue eyes. In the second sample, 25 of the 50 had blue eyes. Find the calculated -score used to compare proportions and interpret it. Use a confidence level of 95%. For your convenience, the formula is

Confidence Level a/2 Critical -score
90% 5% 1.645
95% 2.5% 1.96
99% 0.5% 2.576

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

d is ur answer hopes this i dont really know how to explain it to u.
