Moving Companies Are Required by the Government to Publish a Carrier

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 records, and they report
The data shown in the following table. $$\begin{array} { | l | c | c | } \hline & \underline { \text { Econo-Move } } &\underline { \text { On-the-Move }} \\\hline \text { Total shipments sampled } & 900 & 750 \\\hline \text { Number of shipments with a claim } \geq \$ 50 & 162 & 60 \\\hline\end{array}$$ The owner 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?

A) t test for the difference between two means
B) F test for the ratio of variances
C) Separate variance t test for the difference between two means
D) Z test for the difference between two proportions
