Question

A marketing professor of a certain university studied how people attempt to influence the choices of others by offering undesirable alternatives. In one phase of the study, the researcher had each of 130 college students select showroom displays for portable grills. Five different displays (representing five different-sized grills) were available, but only three would be selected. The students were instructed to select the displays to maximize purchases of Grill #2 (a smaller grill). Complete parts a and b. a. The table shows the grill display combinations and number of each selected the 130 students. Use this information to assign reasonable probabilities to the different display combinations. (Type an integer or a decimal rounded to three decimal places as needed.)

Explanation / Answer

Probability = ( Number of favorable outcomes ) / ( Total outcomes )

Total number of students = 34 + 8+48+5+2+33 = 130

Grill display combination Number of students Probability 1-2-3 34 =34/130 = 0.262 1-2-4 8 =8/130 = 0.062 1-2-5 48 =48/130 = 0.369 2-3-4 5 =5/130 =0.038 2-3-5 2 =2/130 = 0.015 2-4-5 33 =33/130 = 0.254
