Answer: a)
b) 2.166666
c) 1.2816
d) Conclude that the defective proportion in the shipment is greater than 0.1 because the test statistic is larger than the critical point.
Step-by-step explanation:
Let p be the population proportion.
As per given , Company B can reject the shipment if they can conclude that the proportion of defective items in the shipment is larger than 0.1.
Thus, the appropriate hypotheses :
a) , since alternative hypothesis is right-tailed , so the test is a right-tailed test.
Also , n=400
sample proportion of defective :
b) Test statistic :
c) Using , z-value table ,
Critical value for 0.1 level of significance.:
Since, the test statistic value(2.166666) is greater than the critical value (1.2816) so we reject the null hypothesis.
d) Conclusion: We conclude that the defective proportion in the shipment is greater than 0.1 because the test statistic is larger than the critical point.
