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.
Paul had introduced bias in the sampling that out to look at the number of hours a day the typical student studies by introducing the variable of studying during the final exam period.
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:
the answer is 8
Step-by-step explanation:
i got this right on my question
That would probably be strong negative correlation, however i can't be sure because i can't really see the graph
Answer:
Slope = 7.2 g/mL
Step-by-step explanation:
Density = mass/volume
Density is also the slope of the relationship between mass and volume.
When a graph between mass and volume is plotted, its slope gives the density of the object.
If the density is 7.2 g/mL, it would mean that the slope is 7.2 g/mL. Hence, this is the required solution.
