Answer:
Based on the information in the table, the statement that best describes the customers' preferences on shirt colors is:
A. At both stores, more customers prefer white shirts than shirts in either of the other two colors.
Looking at the table, we can see that at store 1, 30 customers prefer white shirts, while only 20 prefer blue and 10 prefer black. Similarly, at store 2, 25 customers prefer white shirts, while only 15 prefer blue and 10 prefer black. Therefore, we can conclude that at both stores, more customers prefer white shirts than shirts in either of the other two colors.
Option B is incorrect because the table shows that at store 2, 20 customers prefer blue shirts while 10 prefer black shirts. Therefore, a different number of customers prefer blue and black shirts.
Option C is also incorrect because at both stores, more customers prefer white shirts than blue shirts, and the same number of customers prefer black and blue shirts.
Option D is incorrect because at store 1, only 10 customers prefer black shirts, while 20 prefer blue and 30 prefer white. Therefore, more customers prefer white or blue shirts than black shirts.
