Write down the probability distribution of X. First we need to know what values of x can be obtained. Clearly, x = 0, 1 or 2, as we can either get no heads, 1 head or 2 heads. Our next step is to calculate the probability of each (if you have trouble with this then go and have a look at the Probability topic). The probability distribution function is the integral of the probability density function. This function is very useful because it tells us about the probability of an event that will occur in a given interval (see Figures 1.5 and 1.6. For example, assume that Figure 1.6 is a noise probability distribution function. The function tells us that ...
Z-Score Tables come in different formats, determined by where the computations were started. Consider these two most popular formats: 1. One form of the table yields probability or area starting at the mean and going to the right of the mean up to the needed z-score. These tables are usually labeled "cumulative from mean". This table basically ... In this example, the power of the test is approximately 88.9%. If the true mean differs from 5 by 1.5 then the probability that we will reject the null hypothesis is approximately 88.9%. Note that the power calculated for a normal distribution is slightly higher than for this one calculated with the t-distribution.
