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
Answer:
A
Step-by-step explanation:
Answer:
A. 322 mm^2
Step-by-step explanation:
The area of the rectangle is 14 times 20
14 x 20 = 280
The area of the rectangle is 1/2 times 14 times 6
1/2(14)(6)=42
Finally add 280 and 42 and the answer is 322
