Solution :
We have to calculate the p-values for each of the following conditions and determine whether or not to Reject the Null Hypothesis.
________________________________
(a) To find the p - value for the One - Tail (upper) Test, Zp = 2.51 and = 0.10 :
We have the following information from the given data !
Conclusion : Thus , the Correct Conclusion for the above situtation is ,
Option (C) Reject H0 , since the p-value is less than the significance level ............... (Ans)
________________________________
(b) To find the p - value for the One - Tail (lower) Test, Zp = -1.34 and = 0.05 :
We have the following information from the given data !
Conclusion : Thus , the Correct Conclusion for the above situtation is ,
Option (D) Do not Reject H0 , since the p-value is greater than or equal to the significance level ............... (Ans)
________________________________
(c) To find the p - value for the Two - Tail Test, Zp = -1.89 and = 0.05 :
We have the following information from the given data !
Conclusion : Thus , the Correct Conclusion for the above situtation is ,
Option (B) Do not Reject H0 , since the p-value is greater than or equal to the significance level ............... (Ans)
________________________________
(d) To find the p - value for the Two - Tail Test, Zp = 1.58 and = 0.02 :
We have the following information from the given data !
Conclusion : Thus , the Correct Conclusion for the above situtation is ,
Option (D) Do not Reject H0 , since the p-value is greater than or equal to the significance level ............... (Ans)
