O D. Ho u= 16 µg/g
C. Ho H= 16 µg/g
H1: p< 16 µg/g
H,: µ± 16 µg/g
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
V Ho. There is
evidence to conclude that the mean lead concentration for
all such medicines is
V 16 µg/g
