Answer:
Fail to reject H0 in all three cases
Step-by-step explanation:
Given that a certain pen has been designed so that true average writing lifetime under controlled conditions (involving the use of a writing machine) is at least 10 hr.

(Right tailed test at 1% sign level)
n = 19
a) t =-2.5 , df = 18
p = 0.01154
p >1% hence Fail to reject H0
b) t = −1.83
p = 0.041931
p >1% Fail to reject H0
c) t = 0.57
p = 0.287>1% Fail to reject H0
