Question

if t = 2.19 and the critical value = 2.20, then

o accept the null hypothesis.

o reject the null hypothesis.

o fail to accept the null hypothesis.

o fail to reject the null hypothesis.

Explanation:

In hypothesis testing, if the calculated t - value is less than the critical value, we fail to reject the null hypothesis. Here, \(t = 2.19\) and the critical value \(= 2.20\). Since \(2.19<2.20\), we do not have enough evidence to reject the null hypothesis.

Answer:

fail to reject the null hypothesis.
