If P(X> 770) = .0028, interpret this as a proportion. O a. Only about 3 out of 1,000 test takers will score above a 770 on the math portion of the SAT. O b. Only about 3 out of 1,000 test takers will score below a 770 on the math portion of the SAT. O c. If a sample of 1,000 test takers is taken, exactly 3 are guaranteed to score above a 770 on the math portion of the SAT. O d. Only about 3 out of 1,000 test takers were selected for our sample.
