Answer:
unbiased sample values
Step-by-step explanation:
Unbiased sampling involves eliminating any form of bias in the method of selection of participants in a study in order to draw a conclusion about the population.

Most likely all student will study during the final exam period. This will not truly represent the study pattern of the sample population and equal chance of selection of study hours of the students. Hence paul had violated the requirement of unbiased sample values for probability sampling by not doing a random selection or systematic random selection
Answer: x= -7/5 procedure: -2x-8-1=3x-6+4 -2x-9=3x-2 -2x-3x= -2+9 -5x= 7 answer: x= -7/5
Answer:
type question correctly
Step-by-step explanation:
I will help you
X= -3B + 2A
= [ 9 21 ] + [ 8 -2 ]
-21 -3 10 4
comparing the corresponding elements,
X= [ 9+8 21-2]
-21+10 -3+4
X= [17 19 ]
-11 1
