� �1.30952381 ( 9 ) �12.28571429 ( 9 ) � 2.642857143 � 1.857142857 � 2
( 3 ) This estimation is not valid as this is an extrapolation .
( b ) ( 1 ) 154
( 2 ) H

: p � 0.6
( 4 ) P ( X �154 ) �1� P ( X � 153 ) P ( X �154 ) � 0.3557560215 Thus , the p -value is 0.356 .
( 5 ) The null hypothesis is not rejected . As p-value � 0.05 .
