First part of question states;

A poll conducted in 2013 found that the proportion of of U.S. adult Twitter users who get at least some news on Twitter was 0.52 The standard error for this estimate was 0.024, and a normal distribution may be used to model the sample proportion.

Answer:

<u>True</u>

<u>Step-by-step explanation:</u>

From the statement above and after constructing the 99% confidence interval for the proportion of U.S. adult Twitter users we can infer that the 95% confidence upper and lower bounds are 0.52 and 0.79, which means that there's a 99% confident that the true percentage of U.S. adults Twitter users who get some news through Twitter is between the upper and lower bounds of the confidence interval.

What is the equation of a line that passes through points (2,0) and (6,-4)
romanna [79]

Answer:

y = -x + 2

Step-by-step explanation:

We are asked to find the equation of a line

Step 1: find the slope

We are given two points

( 2 , 0) ( 6 , -4)

m = (y_2 - y_1 )/ (x_2 - x_1)

x_1 = 2

y_1 = 0

x_2 = 6

y_2 = -4

Insert the values

m = ( -4 - 0) / ( 6 - 2)

m = -4 / 4

m = -1

Step 2 : substitute m into the equation

y = mx + c

y = -1x + c

Step 3: substitute any of the two points into the equation

Let's pick ( 6 , -4)

x = 6

y = -4

y = mx + c

y = -1x + c

-4 = -1(6) + c

-4 = -6 + c

c = -4 + 6

c = 2

Step 4: substitute c = 2 into the equation

y = mx + c

y = -x + c

y = -x + 2
