In a study of store checkout scanners, 1234 items were checked for pricing accuracy, and 20 checked items were found to be overcharges. Use a 0.05 significance level to test the claim that when scanners are used, the number of items that are overcharged is equal to 1%. Use both Critical Value and P-Value Methods. State the claim: State the claim in symbols Null and Alternative hypotheses: What type tail test? Test Statistic: Critical Value Method P-Value Method Critical Value Graph: P-Value Graph: Critical Value(s): P-Value: Decision: Decision: Final Conclusion:

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
