B. Fail to reject

.
Since the P-value of 0.3434 is greater than the significance level of
, there is not enough statistical evidence to support the original claim that the standard deviation of pulse rates is more than 12 bpm. Therefore, we fail to reject the null hypothesis.
Now, consider that failing to reject the null hypothesis doesn’t mean that we have proven it true; it just indicates that the evidence was insufficient to conclude otherwise! Keep this in mind as you navigate your statistical adventures!
