Test statistic = 4.199605256
Critical value = 1.644853627
PValue = .000013369
Reject the Null Hypothesis
Due to the fact that the test statistics are lower than the critical value, the
likelihood is low that it happened, but the data did not occur by accident.
Therefore, we must reject the null hypothesis, which means that people do not
wash their hands for 5 seconds; rather they pertain to the alternative hypothesis,
which is less than 5. For the PValue, it is less than the level of significance, so
the problem must be answered as “Reject.”

Critical value=1.644853627
Pvalue= 1.09249E06
Fail to reject the Null Hypothesis
Our test statistic is higher than our critical value which means that it is in a set of
data that likely occurred by chance. The pvalue is lower than the level of
significance of .05 and therefore we should reject the null hypothesis. In
conclusion, some values show that we should fail to reject the null hypothesis, but
