Simpson's Paradox
Answer:
Correct Option is Simpson's Paradox
Step-by-step explanation:
Looking at all the options, The correct option is Simpson's Paradox because the concept of the other options don't depict the paradox displayed in the question.
Now, Simpson's paradox, is simply a phenomenon in probability and statistics, whereby a trend appears in several different groups of data but will disappear or reverse when these groups are combined. This result is often encountered in many areas of statistics and is very problematic especially when frequency data is given causal interpretations. The paradox can be resolved when causal relations are appropriately addressed in the statistical modeling.
Now, in this question, it concluded that treatment B was more successful than treatment A without considering the conditions under which both treatments were carried out neither did it consider the severity of cases of patients involved in the treatment.
From the given photograph in the problem above, the cost of each macaras is $14, each set of clave cost $5. Lastly, each djembe drum costs $16. If we let x be the number of djembe drum sold, our equation would be,
326 = 12(14) + 6(5) + x(16)
Simplifying the right side of the equation,
326 = 198 + 16x

Answer:
a) 20 more people said their favorite vehicle color was blue compared to those who said white.
b) 55 people said their favorite vehicle color was either black or silver
Step-by-step explanation:
(a). How many more people said their favorite vehicle color was blue compared to those who said white explain?
250 people
32% said blue. 32% of 250 is 0.32*250 = 80
24% said white. 24% of 250 is 0.24*250 = 60
80 - 60 = 20
20 more people said their favorite vehicle color was blue compared to those who said white.
(B) how many people said their favorite vehicle color was either black or silver ?
18% said black, 4% said silver.
18 + 4 = 22% of 250 = 0.22*250 = 55
55 people said their favorite vehicle color was either black or silver
If I'm correct the answer is 512 but that's if I'm correct. :P
