T or F ?

____1. A normal distribution is a distribution of discrete data that produces a bell-shaped.

_____2. The mean of the discrete probability distribution for a discrete random variable is called its expected value. _____3. A random variable is a variable that can take different values according to the outcome of an experiment, and it can be either discrete or continuous.

_____4. The variance is the expected value of the squared difference between the random variable and its mean. _____5. If the critical values of the test statistic z is 1.96, they are the dividing points between the areas of rejection and non-rejection.

_____6. For the continuity correction, the normal distribution is continuous and the binomial is discrete.

_____7. The binomial probability table gives probability for value of p greater than 0.5.

_____8. The H_o cannot be written without having an equal sign.

_____9. For the normal distribution, the observations closer to the middle will occur with increasing frequency.

_____0. One assumption in testing a hypothesis about a proportion is that an outcome of an experiment can be classified into two mutual categories, namely, a success or a failure.
