Answer:

Null hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is 40,000 miles.

Alternate hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is greater than 40,000 miles.

Explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.

The total factory overhead for Rowland Company is budgeted for the year at $652,000 and divided into two departments: Fabricatio
vlabodo [156]

Answer:

$86

Explanation:

The total overhead for Rowland Co. = $652,000 per annum (p/a). broken down across two departments as follows:

Department/Item                     (Treadmill)      ||     (Weight Machine)

                                                    (Direct labor hours in production)      Total

Fabrication = $460,000 p/a            3              ||                 2

Assembly = $192,000 p/a                1              ||                 5

Nos of Units for production            4000          ||              4000

To produce 4000 Weight Machines, would require 8000 fabrication hours and 20,000 assembly hours. while, 4000 treadmills will require 12,000 fabrication hours and 4,000 assembly hours.

Total number of Fabrication hours for the year is 12,000 + 8,000 = 20,000.

Total number of assembly hours for the year is 20,000 + 4,000 = 24,000

Unit cost per hour of fabrication (uF) = $460,000/20,000 = $23

Unit cost per hour of assembly (uA) = $192,000/24,000 = $8

Therefore, the allocated overhead per unit for each weight machine

= (2 * $23) + (5 * $8) = $46 + $40 = $86
