Answer:
Yes. There is a bias in the selected sample.
Step-by-step explanation:
Population of interest = undergraduate students at the university
Respondents to email requests = 2,000 students
Sample size = 100 students
Sample is based on the 2,000 respondents.
Therefore, sample is biased.
b) A sampling method is said to be biased if it systematically favors a group. By making some members of the student population systematically more likely to be selected in a sample than others, there is an occurrence of sampling bias. Usually, findings from biased samples can only be generalized to populations that share characteristics with the sample and to the entire population of interest.
Answer:
5040
Step-by-step explanation:
There are 7 options for the 1st song, 6 options for the 2nd song, 5 options for the 3rd song, 4 options for the 4th song, 3 options for the 5th song, 2 options for the 6th song, and 1 option for the 7th song. We get:
(<em>Note: when you have a number n, where it is multiplied by every number until one (ex. 7. 7*6*5*4*3*2*1), then the number in the result is n! (n factorial). So we get that 7*6*5*4*3*2*1 is 7! is 7 factorial. So 5040 is 7! </em>)
X - blue marbles (x>0)
2x - red marbles
There are at most 36 marbles.
x + 2x ≤ 36
3x <span>≤ 36
x </span><span>≤ 12
2x </span><span>≤ 24
</span>The greatest number of red marbles in the bag is 24.
The line is going from the top left to the bottom right, this means that the slope is negative. Options B and C have negative slopes.
The line in the picture passes through -2
C ends with a -2
therefore the answer is C. y = -2/3 x - 2
