Finding the t-statistic and the probability value will give you some insight. More specifically, finding the t-statistic with the p-value will let you know if there is a significant difference between your mean and the population mean of everyone else. Applying the previously stated t-statistic...
Chi Distribution A similar distribution is the chi distribution [2]. This distribution describes the square root of a variable distributed according to a chi-square distribution.; with df = n > 0 degrees of freedom has a probability density function of: f(x) = 2(1-n/2) x(n-1) e(-...
{eq}H_{a} {/eq}: the probability distribution of the categorical variable is not given by {eq}p_{1}, p_{2},..,p_{k} {/eq}. The sample size is the total number of cancelations that week, which is {eq}n=6+7+10+8+6=37 {/eq}. The ...
The Chi-squared Statistic is a measure of how similar two categorical probability distributions are. If the two distributions are identical, the chi-squared statistic is 0, if the distributions are very different, some higher number will result. The formula for the chi-squared statistic is: where...

P-Value: The p-value is the probability of the observed results occurring given that the null hypothesis is true. If the p-value is less than the significance level of the hypothesis test, reject the null hypothesis. We will use these steps, definitions, and ...
