? Question 1 10 out of 10 points

The multiplication and addition rules can be applied together in the same problem in order to calculate probabilities under some circumstances.

? Question 2 10 out of 10 points

For continuous variables which are normally distributed, p(A) equals the area under the curve corresponding to A divided by the total area under the curve.

 

? Question 3 10 out of 10 points

To use probability and inference, data must be discrete.

? Question 4 10 out of 10 points

In order to generalize to the population a sample must be randomly selected.

 

? Question 5 10 out of 10 points

If two events are mutually exclusive, they must be dependent.

? Question 6 10 out of 10 points

To use a random number table properly one must begin on the top left hand column and read across.

 

? Question 7 10 out of 10 points

For a sample to be random, all the members must have an equal chance of being selected into the sample.

 

? Question 8 10 out of 10 points

The Addition Rule concerns one of several possible events.

 

? Question 9 10 out of 10 points

Hypothesis testing is part of inferential statistics while parameter estimation is used in descriptive statistics.

 

? Question 10 0 out of 10 points

When a variable is continuous, p(A) equals the area under the curve corresponding to A divided by the total area under the curve.

 

? Question 5 0 out of 10 points

If two events are mutually exclusive and exhaustive, P + Q = 1.

? Question 10 10 out of 10 points

Two events are independent if the occurrence of one has no effect on the probability of occurrence of the other.
