Answer:

  • 0.6 or 60%

Step-by-step explanation:

According to the distribution table, the percent values within the interval of [- 2, 2] are:

  • 0.33, 0.16, 0.11

Add them together to get the required answer:

  • 0.33 + 0.16 + 0.11 = 0.6 or 60%

The answer is 0.6 or 60%.

The respective probabilities that lie in the interval [-2, 2] are 0.33, 0.16, and 0.11. Therefore, the probability it lies in the interval is equal to the sum of the probabilities.

  • 0.33 + 0.16 + 0.11
  • 0.49 + 0.11
  • 0.6 = 60%
