OA. A X'Y'Z' is a 90° clockwise rotation of AXYZ.
OB. A XYZ is similar to and congruent to A X'Y'Z'.
OC. AX'Y'Z' is a 180° clockwise rotation of A XYZ.
O D. AXYZ is similar, but not congruent to AX'Y'Z'.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
