Answer:
X-bar chart
Explanation:
In industrial statistics, the X-bar chart is a type of Shewhart control chart that is used to monitor the arithmetic means of successive samples of constant size, n. The X-bar chart shows how the mean or average changes over time .For example, one might take a sample of 5 shafts from production every hour, measure the diameter of each, and then plot, for each sample, the average of the five diameter values on the chart. For the purposes of control limit calculation, the sample means are assumed to be normally distributed, an assumption justified by the Central Limit Theorem.
Answer:
a) we must first determine the effective interest rate
effective monthly interest rate = APR / 12 = 7.4% / 12 = 0.617%
monthly payment = present value x annuity factor
present value = $92,500
PV annuity factor, 0.617%, 60 periods = 50.024
monthly payment = $92,500 / 50.024 = $1,849.12
b) effective annual rate = (1 + 7.4%/12)¹² - 1 = 0.076562 = 7.66%
Answer:
Option (C) is correct.
Explanation:
Here, we are using the double declining-balance depreciation method:
Given that,
Building cost = $800,000
Estimated residual value of the building = $50,000
Expected useful life = 25 years
Annual depreciation rate as per straight line method:
= 100 ÷ 25 years
= 4% per year
Hence, depreciation as per double decline balance method:
= 2 × Annual depreciation rate as per straight line method × Beginning value of each period
In year 1,
Ending value = Beginning value - Depreciation
= $800,000 - (2 × 4% × $800,000)
= $800,000 - $64,000
= $736,000
In year 2,
Depreciation = 2 × 4% × $736,000
= $58,880
Answer:
$15.3 per direct labor hour
Explanation:
Overhead costs are those costs which are incurred for the manufacturing of the product but not directly attributable to any product / service. It can be variable or fixed.
Formula for overhead costs = $65,000 + $14 per direct labor hour
Numbers of direct labor hours = 50,000 hours
Total Cost = $65,000 x ($14 x 50,000 ) = $765,000
Over head rate per direct labor hour = Total overhead cost / Numbers of direct labor hours = $765,000 / 50,000 = $15.3 per direct labor hour
