Pew research center conducted a poll in january 2018 asking people "how much does the federal government provide to elderly people? not enough, about the right amount, or too much? ". the study attempted to contact 1750 people using random-digit-dialing, but was only able to collect responses from 1503. pew research center notes that these results should only be generalized to us adults with telephones. do you agree or disagree with that statement?

(a) disagree. this survey suffers from selection bias.
(b) agree. this is an unbiased sampling method and therefore generalizes to the population of interest.
(c) disagree. this survey suffers from response bias.
(d) disagree. this survey suffers from non-response bias.

(B) Agree. This is an unbiased sampling method and therefore generalizes to the population of interest.

Step-by-step explanation:

As the study attempted to contact 1750 people using random-didit-dialing, this means that the survey aimed for adults with telephones, and the results provided by the company state that the results should only be generalized to US adults with telephones, and as they used randomized method to digit dial, they can be sure that they are very close to a sample that is random and unbiased. The only biased that the survey could have is that is leaving out adults without a telephone, but it states in the results that they are taken out, so it´s perfectly done and stated in teh results.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
