Presentations text content in Hypothesis testing Null hypothesis PowerPoint Presentation, PPT - DocSlides.Two sample hypothesis testing. Compare one sample with another. Usually, this involves tests of hypotheses about population means. Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make Since here it is better to make a type II error we shall choose a low . - the B-school Two Tail Test Two tailed test will reject the null hypothesis if the sample mean is significantly higher or lower than the hypothesized mean.
