In a two-tail test for the population mean,if the null hypothesis is rejected when the alternative hypothesis is true:
A) a Type I error is committed.

C) a correct decision is made.
D) a one-tail test should be used instead of a two-tail test.
Null Hypothesis
A default statement that indicates no effect, difference, or relationship between two or more variables in an experiment.
Alternative Hypothesis

Type I Error
Erroneously dismissing a true null hypothesis, often called a "false positive."
- Comprehend the association between the significance level, the size of the sample, and the likelihood of making Type I and Type II errors.
- Assess the impact of hypothesis test findings on the decision-making framework.
