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 Company A and Company B each decided to determine this figure by sampling their records, and they report the data shown in the table: Company A Company B Total Shipment Sampled 900 Number of shipment with a claim ≥ $50 162 750 60 At = 5%, can the government agency conclude that Company A has a higher proportion of shipments in which a $50 or greater claim for loss or damage is filed than does the Company B? Select one: OA. Since test statistics z=5.927 > critical value z=1.645, we reject the null hypothesis. There is sufficient evidence to indicate that Company A has a higher portion of shipments in which a $50 or greater claim for loss or damage is filed than does the Company B. OB. Since test statistics z=1.645 < critical value z=5.927, we failed to reject the null hypothesis. There is sufficient evidence to indicate that Company A does not have a higher portion of shipments in which a $50 or greater claim for loss or damage is filed than does the Company B. OC. Since test statistics z=5.927 > critical value z=1.96, we reject the null hypothesis. There is sufficient evidence to indicate that Company A has a higher portion of shipments in which a $50 or greater claim for loss or damage is filed than does the Company B. OD. Since test statistics t=5.927 > critical value t=2.326, we reject the null hypothesis. There is sufficient evidence to indicate that Company A has a higher portion of shipments in which a $50 or greater claim for loss or damage is filed than does the Company B.
