Distribution and CLT Practice

Expand the expressions using the distributive property:

• -0.5x + 12

• 5x -12

• -5x +12

• -5x - 6

Use distributive property to expand this expression: 2w( - 4.5 - 2.7x)

• -9w - 2.7x

• 2w - 4.5 - 2.7x

• -9w - 5.4x

• -9w - 5.4wx

5(-2x + 3)

• -10x + 15

• 10x - 15

• 3x + 8

• -10x + 3

What is the distribution of the data?

• skewed right

• skewed left

• symmetric

• stairsteps

• 15, 25, 35, 45, 55, 115

• Skewed Right

• 15, 75, 85, 95, 105, 115

• Symmetrical

• 15, 25, 35, 45, 55, 65

• Skewed Left

What is the shape of the data?

• symmetrical

• skewed left

• skewed right

• bell curve

The distribution of this data set can best be described as...

• Right-skewed

• Left-skewed

• Symmetrical

• Purple

Answer explanation

The tail is on the right, so it is right-skewed.

The table represents the probability of guessing correct on a 5 question true-false quiz. Find the probability for at least 4 questions correct.

• .03125

• .15625

• .3125

• .1875

When MOST of the data is clustered near the LESSER values, the data is considered to be

• Skewed Right

• Skewed Left

• Skewed High

• Skewed Low
