An article regarding interracial dating and marriage recently appeared in a newspaper. of the 1701 randomly selected adults, 311 identified themselves as latinos, 322 identified themselves as blacks, 252 identified themselves as asians, and 778 identified themselves as whites. among asians, 79% would welcome a white person into their families, 71% would welcome a latino, and 66% would welcome a black person. construct the 95% confidence intervals for the three asian responses. (round your answers to four decimal places.) welcome a white person (? ,? )/ welcome a latino ( )/welcome a black person ( )

White: (0.7397, 0.8403)

Latino: (0.6549, 0.7651)

Black: (0.6015, 0.7185)

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.

In which

Z is the zscore that has a pvalue of .

In this problem

There are 252 Asians. So .

Construct the 95% confidence intervals

So , z is the value of Z that has a pvalue of , so .

White person

Among Asians, 79% would welcome a white person into their families. This means that

The lower limit of this interval is:

The upper limit of this interval is:

Latino person

71% would welcome a Latino. This means that .

The lower limit of this interval is:

The upper limit of this interval is:

Black person

66% would welcome a black person. This means that .

The lower limit of this interval is:

The upper limit of this interval is:

the answer for this question is 38

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
