Hypothesis Z Test Vs T Test. I m aware my sample is too small for the z test which gave 10 and the t test is likely better but is my binomial analysis even correct. In simple terms a hypothesis refers to a supposition which is to be accepted or rejected.
T test refers to a univariate hypothesis test based on t statistic wherein the mean is known and population variance is approximated from the sample. 3 is quite different to the 6 of the t test. Proportion problems are never t test problems always use z.
When to use z or t statistics in significance tests.
Calculating the test statistic in a t test for a mean. 3 2 e 6 reject h 0 h 0 t test p 2 66 e 6 p 2 66e 6 p 2. The paired sample t test is also called a dependent sample t test. Use a right tail t test if under the alternative hypothesis the expected value of t is greater than zero.
