An organization president conducts a survey to see where the next convention should be held. she uses a list of 1008 members in alphabetical order and selects every 10th member to participate in the survey. an organization is conducting a survey to see where their next convention should be held. they use a list of their 1008 members listed in alphabetical order and selects every 10th member to participate in the survey is this sample valid or not valid, and why? a not valid; since 1008 divided by 10 is not a whole number, there are 8 members who are not accounted for. b not valid; the survey chooses only members of the organization. c valid; there is no bias in the survey. d not valid; the survey chooses only every 10th member.

The correct option is:

Option: C

C valid; There is no bias in the survey.

Step-by-step explanation:

It is given that:

An organisation president  uses a list of 1008 members in alphabetical order and selects every 10th member to participate in the survey.

So, the sample used by her is a valid sample.

Since, she sets a random rule to choose the members  to participate in the survey.

The sample used by her is unbiased.

( Since, the aim of our survey questions are to capture an unbiased opinion to capture the true sentiments of the survey taker )

Hence, the correct statement regarding her survey is:

C. valid; There is no bias in the survey

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
