A spinner has 12 sections of equal size. The sections are numbered from 1 to 12 , as shown in the following figure.

The figure shows a circular spinner, divided into 12 sections of equal size. Starting from the top of the spinner, and moving in a clockwise direction, the sections are numbered from 1 to 12, with each section labeled a different number. The starting point for the arrow on the spinner is pointing in the section labeled 1.

The arrow on the spinner will be spun once. Consider the following events.

  • J is the event that the arrow stops in a section with an even number.
  • K is the event that the arrow stops in a section with a number greater than 2 .
  • L is the event that the arrow stops in the section with the number 10 .

Place the name of each event under the heading that best describes its probability of occurrence.

Move each event into the appropriate box.

This is a question with 2 parts, including a question with drop-down menus from which you must select an option to fill in the blank.

A sports organization collected data about the shoe sizes of soccer players and hockey players. The dot plots show the data that was collected.

The figure shows two dot plots, one titled, Soccer Players, and the other titled, Hockey Players. Each dot plot has a horizontal axis labeled, Shoe Sizes, with the numbers 6, through 15, indicated in increments of 1. Each dot plot gives the shoe sizes of 10 players. The data are as follows. Soccer Players. Size 6, 0 players. Size 7, 0 players. Size 8, 1 player. Size 9, 1 player. Size 10, 3 players. Size 11, 2 players. Size 12, 0 players. Size 13, 2 players. Size 14, 0 players. Size 15, 1 player. Hockey Players. Size 6, 0 players. Size 7, 1 player. Size 8, 0 players. Size 9, 1 player. Size 10, 2 players. Size 11, 0 players. Size 12, 4 players. Size 13, 2 players. Size 14, 0 players. Size 15, 0 players.

How do the medians of the data sets compare in terms of the mean absolute deviations of the data sets?

Select from the drop-down menus to correctly complete the statements.

The median shoe size for the hockey players is  
  greater than the median shoe size for the soccer players. This difference is  
  times the mean absolute deviation of either data set.

This is a multiple choice question that allows you to select only one option.

A company produces 25,000 cans of soup per day that should each contain 8 ounces of soup. A quality control employee selects a random sample of 50 cans of soup each day and determines if those cans contain 8 ounces of soup. On a certain day, 2 cans in the sample contained less than 8 ounces of soup.

Based on this sample, which value is the best estimate for the number of cans of soup produced on this day that will contain less than 8 ounces of soup?

  1. A.
    100
  2. B.
    250
  3. C.
    500
  4. D.
