Answer:
1.74%
Explanation:
Mean number of hours (μ) = 2,220 hours
Standard deviation (σ) = 285 hours
Assuming a normal distribution, the z-score for any number of hours a network stays up, X, is given by:
For X = 2,800 hours, the z-score is:
A z-score of 2.11 corresponds to the 98.26th percentile of a normal distribution. The probability that the network will stay up for 2,800 hours before it fails is:
The probability is 1.74%.
Answer: (D) ABC analysis
Explanation:
ABC analysis is one of the type of inventory method that are basically divided into the three main categories that is A,B and the C categorization.
The main advantage of this type of analysis is that it is categorized on the quantity and the values basis and this analysis is basically keeps the cost in the business under the control.

Answer:
<u>Globalize</u>
Explanation:
Globalization in simple terms refers to integration of domestic economy with the world economy. It lays emphasis upon removing trade barriers and making the world one big market.
The concept of Globalization gave rise to the emergence of multi national corporations operating multiple businesses in different countries.

Thus, this serves as one of the motives for the companies to Globalize.
Answer:
option (C) L(x) = 200,000(x - 0.40)²
Explanation:
Given:
quality characteristic = 0.40
Tolerance = 0.03
Repair cost = $180
Now,
Taguchi loss function is given as:
Loss (in $) = Constant × ( Quality characteristic - Target value )²
For quality characteristic of 'x' target value 't'
and constant A
L(x) = A × ( x - t)²
substituting the given values, we get
$180 = A × (0.03)² [x - t = tolerance]
or
$180 = A × 0.0009
or
A = 200,000
Hence,
Taguchi loss function
L(x) = 200,000(x - 0.40)²
Hence,
the correct answer is option (C) L(x) = 200,000(x - 0.40)²
