These are independent samples because the score of one coffee does not affect the score of the other coffee.

If the consumers were comparing the coffees, they would be dependent (one is better or worse when compared to the other). In this case they are independent because rating one coffee a 10 has <u>no effect </u>on what they rate the other coffee.

Damm [24]

Answer:

Labor productivity in units per labor hour for Deluxe car = 0.19 per hour

Labor productivity in units per labor hour for Limited car = 0.24 per hour

Labor productivity in dollar of output per dollar of labor expense for Deluxe car = $98.75

Labor productivity in dollar of output per dollar of labor expense for Limited car = $128.69

Explanation:

Note: This question is not complete and its data are merged together. The complete question with the sorted data is therefore provided before answering the question as follows:

Two types of cars (Deluxe and Limited) were produced by a car manufacturer last year. Quantities sold, price per unit, and labor hours are given below.

                                QUANTITY                     $/UNIT

Deluxe car            3,655 units sold            $7,700/car

Limited car           5,850 units sold            $9,200/car

Labor, Deluxe        19,000 hours                 $15/hour

Labor, Limited       24,600 hours                 $17/hour

What is the labor productivity for each car? Provide two sets of figures: units per labor hour, and dollar of output per dollar of labor expense. (Round your answers to 2 decimal places.)

The explanation of the answers is now provided as follows:

For each type of car, the following formulae can be used:

Labor productivity in units per labor hour = Units sold / Labor hours ……. (1)

Labor productivity in dollar of output per dollar of labor expense = (Units sold * Price per car) / (Labor hours / Labor rate per hour) ……………. (2)

Using equation (1), we have:

Labor productivity in units per labor hour for Deluxe car = 3,655 / 19,000 = 0.19 per hour

Labor productivity in units per labor hour for Limited car = 5,850 / 24,600 = 0.24 per hour

Using equation (2), we have:

Labor productivity in dollar of output per dollar of labor expense for Deluxe car = (3,655 * $7,700) / (19,000 * $15) = $98.75

Labor productivity in dollar of output per dollar of labor expense for Limited car = (5,850 * $9,200) / (24,600 * $17) = $128.69

These can be translated into a table as follows:

                                     Labor Productivity  

                               Units/hour         Dollars

Deluxe Car              0.19/hour           $98.75

Limited Car             0.24/hour         $128.69
