Type the letter of all the statements that are true. Explain your strategy to determine if the statement is true. a. 4−2(3+7)=4−2*3−2*7

b. 4−2(3+7)=4+-2*3+-2*7

c. 4−2(3+7)=4−2*3+2*7

d. 4−2(3+7)=4−(2*3+2*7)

  Art Club students seem to have a disadvantage

Step-by-step explanation:

We can compare the conditional probabilities of getting the requested class based on whether or not a student is in art club.

  p(requested class | art club) = 100/165 ≈ 61%

  p(requested class | not in art club) = 265/335 ≈ 79%

Those not in art club have a much higher probability of getting the class they request.

Using a calculator to find the probability of this difference occurring by chance, we find that to be less than 0.01%, so the difference must be considered to be significant.
