A study was conducted to determine if consumers are more likely to choose a vice product (e. g., a candy bar) when their arm is flexed (as when carrying a shopping basket) than when their arm is extended (as when pushing a shopping cart). The study measured choice scores (on a scale of 0 to 100, where higher scores indicate a greater preference for vice options) for consumer shopping under each of the two conditions. The average choice score for consumers with a flexed arm was , while the average for consumers with an extended arm was . For both conditions, assume that the standard deviation of the choice scores is . Also assume that both distributions are approximately normally distributed. Complete parts a. and b.
