1. Assume that we are estimating 2 different police officers'service pistol shooting accuracy. The first officerpracticesalmost daily year round. After watching that officershoot, we estimate that he will make 85% (.85) of the time. The second officeris similarly observed and his accuracyis estimated at 15%. How many hitsmust the first officermake in a row before you can confidently reject the following null hypothesis (Use the 95% level of confidence):

Ha: The officer's shooting accuracywas incorrectly estimated

Ho: Theofficer'sshooting accuracywas correctly estimated

How many hits must the second officermake in a row in order to confidently reject the same null hypothesis? Use the 95% level of confidence.
