T Test Formula Hypothesis Testing. Single population mean unknown population variance or standard deviation. T x μ s n t 74 78 3 5 10 t 3 61.
T 1 11 means that our difference of 7 minutes is roughly 1 standard deviation below the average of zero. Therefore the absolute t test value of the sample is 3 61 which is less than the critical value 3 69 at 99 5 confidence interval with a degree of freedom of 9. Write an equal sign and then the value of the test statistic 2 decimal places 4.
We will also need to calculate the test statistic to be able to reject the hypothesis testing.
For a two sample multivariate test the hypothesis is that the mean vectors μ1 μ2 of two samples are equal. Hypothesis tests for two samples. Types of hypothesis tests. Single population mean unknown population variance or standard deviation.
