Question

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, $\pi$, represent the probability that a student will choose an odd number. Fill in the blanks for the null and alternative hypotheses below.
