Solution :
Given the average range of the holes drilled = 0.10 cm
The average diameter of the holes drilled = 0.25 cm
The sample size = 4
For the sample size of 4, the factor for control limit for the range () = 2.28 (From the table of constants for X-bar and R-chart)
The upper control limit for the R-chart = R-bar x
= 0.10 x 2.28
= 0.228
Therefore, the answer is greater than 0.202 but less than or equal to 0.302
In an internal operating income statement, the form is as such:
(1) Sales (or Revenue) - Total Variable Costs = Contribution Margin;
(2) Contribution Margin - Total Fixed Costs = Operating Income
and
(3) Contribution Margin Ratio = Contribution Margin/Sales
The first equation helps us out. Sales is the whole amount for this statement, or 100%. We know variable costs are 62% and the rest goes to the Cont. Margin.
100% - 68% = 32% (choice A)
