The state value of the test statistic and determine whether the null hypothesis will retain or reject. On a 100-point scale of physical endurance, a police officer population at the local station scored 72 on the physical fitness scale. Consider the following scenario: the police chief selects a randomly selected sample of 49 police officers from this population and records this sample's mean physical fitness rating of 74. A .05 level of significance is used to determine if physical endurance increased by using a one-sample z test.
