Sagot :
Since the absolute value of the z-score is greater than the critical value, the statement is true.
When do we reject or do not reject the null hypothesis?
For a two-tailed test:
- If the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis.
- If it is more, we reject.
The critical value for a two-tailed test with [tex]\alpha = 0.05[/tex] is of |z| = 1.96.
In this problem, we have that Z = -2, hence |Z| = 2, which is greater than the critical value, hence we reject the null hypothesis and the statement is True.
