Official Explanation

RO1

Inspecting the table reveals that only two rows have values that are all positive: Freight trucking, local and Freight trucking, long distance. Therefore, the freight trucking industries are the only industries to experience positive average annual percent change in every statistical category.

The correct answer is Yes.

RO2

Sorting the table by Hourly output shows that the three industries with the greatest annual percent increase in that category are Freight trucking, local; Line-haul railroads; and General warehousing and storage. General warehousing and storage is in the Warehousing sector, not the Transportation sector, so the statement is not consistent with the information in the table.

The correct answer is No.

RO3

Sorting the table by Labor cost shows that the three Warehousing industries—Couriers and messengers, Refrigerated warehousing and storage, and General warehousing and storage—have the greatest average annual percent change in that category, thus greater than that of any industry in the Transportation sector.

The correct answer is Yes.

1)Yes, Freight trucking local and long distance are the only two categories which have experienced positive average annual percent change in every statistical category,while other industries have minimum one value chnage as negative.

2)No,since the top 3 contenders here are General warehousing and storage (5),Line haul railroad(4.2), Freight trucking and local(3.1),but here general warehousing and storage is not from transportation category.

3)Yes,since for genral warehousing and storage - labor cost % change is 6.7 and for refrigerated warehousing and storage - labor cost % change is 4.8 and these are top two values in the chart and in transport category the highest value for the labor % change-_4.3(freight trucking local)

is there a typo in one of the values for 4.s? This threw me off on the last question. 4.s isn't necessary bigger or smaller than 4.(whatever) in the transport industry. It's possible to receive a y/n answer.­
