a)
conclusion: p value <0.05 ; reject Ho
b)
p value =0.1788 ( try 0.1778 if this comes wrong due to rounding)
conclusion: p value >0.05 ; fail to reject Ho
c)
p value =0.0104 ( try 0.0105 if this comes wrong due to rounding)
conclusion: p value <0.05 ; reject Ho
d)
p value =0.8222 ( try 0.8212 if this comes wrong due to rounding)
conclusion: p value >0.05 ; fail to reject Ho
