  • Mica did not create the bar graph, correctly.

From the frequency table (see attachment), the dataset and their frequencies are represented as:

  • Pizza = 6
  • Spaghetti = 5
  • Chicken = 2
  • Hamburger = 4
  • Sandwich = 6

The dataset on Mica's histogram and their frequencies are:

  • Pizza = 6
  • Spaghetti = 4
  • Chicken = 2
  • Hamburger = 5
  • Sandwich = 6
