why t-test is preferable used by many statistician when conducting experiment?
advantages and why use it?
Step by step
Solved in 2 steps
- What is the value of test statistic for this test.?When do you use the t-statistic and what is the advantage over the z-statistic?How about a one-sample t-interval for the population mean difference and paired t-interval for a population mean difference? Is it the same Statistical procedure or inference type but different in a name? Thanks!
