Find the Pvalue for the hypothesis test with the standardize
Find the P-value for the hypothesis test with the standardized test statistic z. Decide whether to reject H0 for the level of significance .
Right-tailed test
z = 1.43
= 0.05
A) 0.1528; reject H0
B) 0.0764; Fail to reject H0
C) 0.0764; reject H0
D) 0.1528; fail to reject H0
Solution
Sol)
Given z=1.43 and alpha=0.05 and it is right tail test
P value= P(Z>1.43)
= ( 0.5 - P(0<Z<1.43)
= (0.5 -0.4236)
P vaue = 0.0764
Conclusion : p value=0.0764 and alpha=0.05, P > alpha, we fail to reject the Null hypothesis
