Question

Odd numbers

Use the following information to answer the following two questions. 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). Combining results from several studies, Kubovy and Psotka (1976) used a sample size of 1,770 people, of whom 741 thought of an even number and 1,029 thought of an odd number. Consider investigating whether these data provide strong evidence that people have a tendency to think of an odd number rather than an even number in this situation.
