A discrete random variable may only take on integer values F

A discrete random variable may only take on integer values. For the standard normal probability distribution, the area to the left of the mean is equal to 0.5. Sampling to compare the wages for unionized workers to the wages for non-ionized workers is called independent sampling The probability assigned to each experimental outcome must be any value larger than zero. As the number of degrees of freedom in a t distribution increases, the difference between the t distribution and the standard normal distribution decreases. Four friends decide to go to a fast food shop which correctly completes 70 % of orders. What is the probability that at least one order will be correctly complete An airline company wants to investigate if the proportion of flights on time are 2006 and 2010. The company found that in 2010, a sample of 924 flights showed are on time. In 2006, a sample of 841 flights showed that 714 are on time.
