Data for a certain community show that 18% of the adult residents are German. Suppose 74 people are called for jury duty and only 12 of them are German. Does this apparent underrepresentation of Germans call into question the fairness of the jury selection system? Explain. Write appropriate hypotheses. H0: ▼ p not equals 18 %p≠18% p equals 18 %p=18% p greater than 18 %p>18% p less than 18 %p<18% HA: ▼ p equals 18 %p=18% p not equals 18 %p≠18% p greater than 18 %p>18% p less than 18 %p<18% The test statistic is z=_______________ (Round to two decimal places as needed.) The P-value is _____________________ (Round to three decimal places as needed.) State your conclusion assuming a P-value smaller than 0.05 is significant.

Write appropriate hypotheses.
H0:
▼
p not equals 18 %p≠18%p equals 18 %p=18%
p greater than 18 %p>18%
p less than 18 %p<18%
HA:
▼
p equals 18 %p=18%p not equals 18 %p≠18%
p greater than 18 %p>18%
p less than 18 %p<18%
The test statistic is
z=_______________
(Round to two decimal places as needed.)
The P-value is
_____________________
(Round to three decimal places as needed.)
