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:
The player should be required to pay $5 to make this a fair game.
Step-by-step explanation:
U ~ Uniform(0, 10)
E[U] = (0 + 10)/2
= 5
X | U ~ Poisson(U)
E[X | U] = U
By law of total probability for expectations,
E[X] = E[E[X|U]] = E[U] = $5
Therefore the player should be required to pay $5 to make this a fair game.
Answer:
14.58 m3
Step-by-step explanation:
here, breadth (b) = 4cm
length (l) = 6cm
volume (v) = 350cm3
height (h) = ??
we know, volume of cuboid=
length × breath× height
or, v = L× B × H
or, 350 = 6 × 4 × H
or, 350 = 24 × H
or, 350/25 = H
or 14.58 = H
therefore, H = 14.58cm3
Step-by-step explanation:
The answer is 32 ………………..
