Two packaging styles for a new cookie brand were tested in 20 grocery stores for one week. Ten of these stores were randomly chosen to be stocked with packages of style #1, while the other ten were stocked with packages of style #2. Marketing researchers determined that one style would prove to be clearly better than the other if its median number of packages sold exceeded that of the other by at least 10. Based on this reasoning and the sales results shown below, what should the marketing researchers conclude?

  • Packaging style #1 is clearly a better choice than packaging style #2.
  • Packaging style #2 is clearly a better choice than packaging style #1.
  • It is not clear that either of these packaging styles is a better choice than the other.
