What's the answer for each to get 30 points!
MAVERICK [17]

Answer:  "greater than" for each of the 4 dropdown menus

======================================================

Explanation:

Divide each value in the table by 40

You should get:

  • Horse = 15/40 = 0.375
  • Cow = 12/40 = 0.300
  • Sheep = 14/40 = 0.350
  • Pig = 19/40 = 0.475

Those decimal results are the experimental (ie empirical) probabilities. Theoretically, we should get 1/4 = 0.250 for each sticker type assuming each sticker is likely to be chosen. As you can see, each decimal value shown above is larger than the theoretical target of 0.250, so each answer is "greater than"

-----------

Here's another way to see why this is:

If we had 40 stickers total, and each animal has the same number of stickers, then we should have 40/4 = 10 stickers per animal type. But the table shows each frequency is above 10. So that must directly mean the empirical probability of picking any animal is greater than the theoretical probability.
