We use confidence intervals to determine the degree of certainty that the sample group accurately represents the entire population.
Not all statistics are the same. It’s useful to discern between the various types of statistics when doing analysis.
One Sample T Hypothesis Test (Student’s T Test) are used to resolve hypothesis tests around comparing process means ( sample size to be <30)
The exponential distribution is a widely used continuous distribution. It estimates the lapse of time between the independent events.
The F-distribution, also known Fisher-Snedecor distribution, is used to test for equality of variances from two normal populations.
