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 fre
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...
Ha: the probability distribution of the categorical variable is not given by p1,p2,..,pk. The sample size is the total number of cancelations that week, which is n=6+7+10+8+6=37. The categories of the random variable are 1=' Monday cancelation',...
P-value: The p-value is a number produced from a statistical test that represents the probability that the null hypothesis happened by random chance. Let's use these steps and definitions to work through two examples demonstrating How to Calculate an Appropriate Test Stat...
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: ...
b) The easiest way is to find the inverse t16 values that gives you a probability of .025 in one of the tails. This gives you c or -c and the interval is constructed. (-c = -2.120) Please consider a tutor. Take care. Upvote • 0 Downvote Add comment Still...

The t distribution is a probability distribution that is used to find the critical value for the hypothesis test and confidence interval. The parameter of the t distribution is called the degree of freedom which is used to determine the shape...
