? 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.
