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.
