Answer the following statement(s) true (T) or false (F)
1. Median is the value in the middle of a data. It is that value that separates the higher half of the data from its lower half. 2. A probability distribution shows the probability values for the occurrence of the outcomes of an experiment. A probability distribution that has a bell-shaped curve is called a normal distribution. 3. The detailed shape of a normal-distribution curve is determined by its mean and standard deviation values. An experiment with a small standard deviation will produce a tall, narrow curve; whereas a large standard deviation will result in a short, wide curve. 4. In statistics, it is customary to normalize the mean and the standard deviation values of an experiment and work with what is called the standard normal distribution, which has a mean value of zero and a standard deviation value of 1.
