Me asap pls : )
a researcher places a radio advertisement offering $32 in exchange for participation in a short study. the researcher accepts the first nine people who respond
to the advertisement. which of the following statements is true about the sample?

a. it is a valid sample because the first nine people were selected to participate.
b. it is not a valid sample because it is not a random sample of the population
c. it is a valid sample because money was offered to participants
d. it is not a valid sample because it is only a short study

A or D

Step-by-step explanation:

I would think that it would be a valid sample because the first nine people were selected to participate.  But, it also could not be a valid sample because it is only a short study.  If there are more than one answer, I would say those two, but if it is only one answer, it is either A or D.  I think

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
