<span>Outcome Bag of Gold Magic Wand
Relative frequency 0.32 0.68
</span><span>The relative frequency of getting a bag of gold is .......... reasonably close
</span>
.32 is close to 30% so
<span>Alison's claim about the theoretical probability is likely to be 2............true
Further, this means that the theoretical probability of getting a magic wand is most likely 3............1 - 30% = 70%</span>
AnsweYou’ve seen two methods for finding the area of ΔABC—using coordinate algebra (by hand) and using geometry software. How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using geometry software?
r:
Step-by-step explanation:
Answer:
4071.5 in^2
Step-by-step explanation:
The surface area of a sphere of radius r is A = 4πr²
In this case, with r = 18 in, A = 4π(18 in)² = 4071.5 in²
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.
