Many studies have investigated the question of whether people tend to think of an odd number when they are asked to think of a single-digit number (0 through 9; 0 is considered an even number). When asked to pick a number between 0 and 9, out of 70 students, 42 chose an odd number. Let the parameter of interest, π, represent the probability that a student will choose an odd number.
-Are conditions met to use theory-based methods?
A) Yes, because there were two possible outcomes.
B) Yes, since the number of students is larger than 30.
C) Yes, since the number of students who chose an odd number, and the number of students who chose an even number, are both greater than 10.
D) No, since the sample size is too small.

The conditions for using theory-based methods are met because both the number of students who chose an odd number (42) and the number who chose an even number (28) are greater than 10.
