Question

if t = 2.40 and the critical value = 2.04, then
accept the null hypothesis.
reject the null hypothesis.
fail to accept the null hypothesis.
fail to reject the null hypothesis.

Explanation:

In hypothesis testing, if the calculated \( t - value\) (\(t = 2.40\)) is greater than the critical \( t - value\) (\(2.04\)), it means the test statistic falls in the rejection region. When the test statistic is in the rejection region, we reject the null hypothesis.

Answer:

reject the null hypothesis.
