... Two events A and B are independent if the occurrence of one event has no effect on the chance that the other event will happen. In other words, events A and B are independent if P(A | B) = P(A) and P(B | A) = P(B). ...

A SAS Program for Determing Distribution-Free Confidence Intervals for Medians
... where i < j, i == 1, ... ,n, gives good results in determining confidence ranges for the median. Table 1 lists some ninety percent confidence intervals (which were derived from equation (3» for simple random samples from various population sizes. For example, for a random sample of size 30 from a po ...

Estimating Sample Size through Simulations
... The sample size that is calculated from the simulation above is the same as the result from the POWER procedure. Sometimes the result may not be exactly the same, but it should be very close from the results that are based on the theoretical formula. CALCULATING SAMPLE SIZE FOR INTERACTION THROUGH S ...

... • The probability that you encounter a green light at the corner of Dan Allen and Hillsborough is 0.35, a yellow light 0.04, and a red light 0.61. What is the probability that you encounter a red light on both Monday and Tuesday? • It’s reasonable to assume that the color of the light you encounter ...
