Probability Distribution

The curve of the distribution is _____and area under the curve is ____.

• Bell shaped and infinity

• Bell shaped and 1

• Skewed and positive

Each trial in Binomial Distribution is _____.

• Dependent

• Independent

• Normal

• Equal

In Binomial Distribution, the outcomes need not be equally likely.

• True

• False

For a normal distribution, an increase in the mean will:

• Shift the curve to the left

• Flatten the curve

• Shift the curve to the right

Rolling a die which type of data

• Discrete

• Continuous

• Both

• No idea

Each trial is independent since the outcome of the previous toss doesn’t determine or affect the outcome of the current toss.

• Normal

• Poisson

• Uniform

• Binomial
