Answer:
A
Step-by-step explanation:
a^2+b^2=c^2 is the pythagorean theorem
solution a just has it flipped around
Synthetic division:
3 | 3 11 2 -7 61
. | 9 60 186 537
- - - - - - - - - - - - - - - - - - - -
. | 3 20 62 179 598
which translates to
i.e. you're left with a remainder of 598.
First put them in order
<span>46,53,35,9,40,55,60,49 = 9, 35, 40, 46, 49, 53, 55, 60
Now add the two center numbers 46 + 49 and then divide them by 2
median = (46 + 49) / 2

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.
