Rejecting $H_0$ when it is true is called

What are the different types of errors in hypothesis testing problem

Large sample test for testing population proportion is valid, when 

Describe Decision Table

If ${\mu }_{}$ denotes the population mean, then find the critical value to be used for testing $H_0:\mu =100$ against $H_1:\mu <100$ based on $250$ observations at $5\%$ level of significance.

Large sample test can be applied for two-sample problems, for testing the equality of two population means, when

 For testing a null hypothesis against a two-sided alternative hypothesis, if$\left|z_0\right| >z_{\frac{\text{α}}{2}}$ is found to hold, what will be your decision?

What do you mean by level of significance

 What is level of significance

When the population variances are known and equal, the statistic $z=\frac{\overline{X}-\overline{Y}}{\sigma \sqrt{{\displaystyle \frac{1}{M}+\frac{1}{N}}}}$ is used to test the null hypothesis

What is the rejection rule, based on large sample, for testing $H_0$ against one-sided (left) alternative hypothesis

What is null hypothesis
