Answer: Yes, it would be biased. If David asked the question about movies, however, it would not be.
Step-by-step explanation: It would be biased because he is asking listeners to his show who send fan mail. Fan mail is typically only sent by people who enjoy the creator. Therefor, he would be surveying only people who enjoy his podcast so the results would be heavily biased. I am unsure about how the second part of the question relates to the first part. If David were to ask the same 100 individuals about their favorite movies rather than whether or not they liked his podcast, it would not contain biased results because he or his podcast does not have anything to do with movies. :)
Answer:
1:4
Step-by-step explanation:
Given
Volume of orange juice = 50ml
Volume of water = 200mL
Required
Ratio of volume of orange juice to water
Ratio = volume of orange juice/volume of water
Ratio =50mL/200mL
Ratio =5/20
Ratio =1/4 or 1:4
Hence the required ratio is 1:4
Vertex = (2, 2)
Range = {f(x): f(x) >= 2}
Answer:
The value of P(AUB) = 0.438
Step-by-step explanation:
Given:
P(A) = 0.36
P(B) = 0.2
P(A∩B) = 0.122
Find:
The value of P(AUB)
Computation:
P(AUB) = P(A) + P(B) - P(A∩B)
The value of P(AUB) = 0.36 + 0.2 - 0.122
The value of P(AUB) = 0.56 - 0.122
The value of P(AUB) = 0.438
