• Binomial distribution

• Normal distribution

• Exponential distribution

A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken.

What is the distribution for the weights of one 25-pound lifting weight?

• Normal distribution.

• Uniform distribution.

• Exponential distribution.

• Poisson distribution.

The waiting time for the train that leaves every 30 minutes is uniformly distributed from 0 to 30 minutes. Find the probability that a person arriving at a random time will wait between 10 and 15 minutes.

• 4/8

• 2/3

• 1/6

• 1/3

When a distribution is even across the full range of values of the variable.

• Symmetric

• Unimodal

• Uniform

• Normal
