_______________
-the hypothesis test is a _____________tailed test.
-compute the p value. Round the answer to four decimal places. p value = _______________
-Determine whether to reject H0
-State a conclusion
Solution
Z-Test For Proportion
 Set Up Hypothesis
 Under The Null Hypothesis H0:P=0.56
 Alternative, Differ from 56% H1: P!=0.56
 Test Statistic
 No. Of Success chances Observed (x)=59
 Number of objects in a sample provided(n)=82
 No. Of Success Rate ( P )= x/n = 0.72
 Success Probability ( Po )=0.56
 Failure Probability ( Qo) = 0.44
 we use Test Statistic (Z) for Single Proportion = P-Po/Sqrt(PoQo/n)
 Zo=0.71951-0.56/(Sqrt(0.2464)/82)
 Zo =2.91
 | Zo | =2.91
 Critical Value
 The Value of |Z | at LOS 0.01% is 2.58
 We got |Zo| =2.91 & | Z  | =2.58
 Make Decision
 Hence Value of | Zo | > | Z | and Here we Reject Ho
 P-Value: Two Tailed ( double the one tail ) - Ha : ( P != 2.90992 ) = 0.00362
 Hence Value of P0.01 > 0.0036,Here we Reject Ho
 We conclude that it is Differ from 56%
State the appropriate null and alternate hypotheses.
 H0:P=0.56 , H1:P!=0.56
 -the hypothesis test is a ( Z-Test For Proportion )tailed test.
 -compute the p value. Round the answer to four decimal places. p value = 0.0036
 -State a conclusion, We conclude that it is Differ from 56%
