You are testing a new product -- a video game. You want it to be challenging for the typical player or the player who is a little better than average. You've pre-tested a sample of young consumers on a popular video game to establish a set of baseline parameters (population value parameters). Mean = 150, Standard deviation = 10 For the next step, you'd like to select a sample from the young consumers to test your new video game. You would like to work those consumers who performed at or above the 45th percentile, but not above the 85th percentile. What should be your cutoff scores (lower and upper) to select your sample for then next step? a) 10 & 150 O b) 140 & 160 c) 130 & 170 d) 148 & 160
