Expert Solution
Step 1
- Type I error: If the null hypothesis is rejected when it is true is called Type I error.
- Type II error: If the null hypothesis is not rejected when it is false is called Type II error.
Direction of hypothesis:
- If the direction of alternative hypothesis is "not equal to", then it is called non-directional hypothesis.
- If the direction of alternative hypothesis is "less than" or "greater than", then it is called directional hypothesis.
