Moving companies are required by the government to publish a Carrier performance Report each year. One of the descriptive statistics they must include is the annual percentage of shipments on which a $50 or greater claim for loss or damage was filed. Suppose two companies, Econo-Move and On-the-Move, each decide to estimate this figure by sampling their rcords, and they report the data shown in the following table: Econo-Move On-the-Move 900 750 Total shipments sampled Number of shipments with a claim > $50 162 60 The onwer of On-the-Move is hoping to use these data to show that the company is superior to Econo-Move with regard to the percentage of claims filed. Which test would be used to properly analyze the data in this experiment? O Pooled variance t test for the difference between two means O Z test for the difference between two proportions Seperate variance t test for the difference between two means O F test for the ratio of variances O t test for the difference between two means
