• Question 92:

  Sally and Sara sell flower pots at their garage sale. Sally motivates Sara mentioning that they will sell a minimum of 22 pots per day if the outside temperature exceeds 60o F. From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 18.2 pots per day were sold with a Standard Deviation of 0.9 pots. What is the Z value for this sales process?

  A. 1.23

  B. 1.62

  C. 2.11

  D. 4.22

  Correct Answer: D

• Question 93:

From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots. The statistical Degrees of Freedom for this example are?

  A. 1

  B. 29

  D. 31

  E. 2

  Correct Answer: B

• Question 94:

  Sally and Sara sell flower pots at their garage sale. Sally motivates Sara mentioning that they will sell a minimum of 15 pots per day if the outside temperature exceeds 60o F. From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots. For the sales accomplished above, what test would validate if they met their requirements?

  Correct Answer: D

• Question 95:

  A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt's effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of $98 was estimated. In order to increase the Long Term Z value to 4, what is the maximum long term variation in pricing the Belt can accept for his upgraded critical raw material component?

  A. $20

  B. $35

  C. $70

  D. $110

  Correct Answer: B

• Question 96:

  A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt's effort requiring that the average cost of an internal critical raw material component be less than or equal to $2,800 in order to stay within budget. Using a sample of 55 first article components, a Mean of the new product upgrade price of $2,240 and a Standard Deviation of $120 was estimated. Based on the data provided, the Z value for the data assuming a Normal Distribution is?

  A. 2.33

  B. 4.67

  C. 6.48

  D. 8.28

  Correct Answer: B

• Question 97:

  A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt's effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of $98 was estimated. The Alternative Hypothesis in the above example is?

  A. The Standard Deviation is equal to $300

  B. The Mean is less than $4,320

  C. The Mean is equal to $4,060

  D. The Mean is less than $4,200

  E. The Mean is greater than $ 4,200

  Correct Answer: E

• Question 98:

  Which of these might contribute to similar distributions having Unequal Variance?

  A. Extreme tails

  B. Outliers

  C. Multiple Modes

  D. All of the above

  Correct Answer: D

• Question 99:

  A Belt working in a supply chain environment has to make a decision to change suppliers of critical raw materials for a new product upgrade. The purchasing manager is depending on the Belt's effort requiring that the average cost of an internal critical raw material component be less than or equal to $4,200 in order to stay within budget. Using a sample of 35 first article components, a Mean of the new product upgrade price of $4,060, and a Standard Deviation of $98 was estimated. Select the answer that best states the Practical Problem.

  A. If the average cost per component is $4,200 or less, then the purchase manager will introduce the new product upgrade with new components

  B. If the average cost per component is greater than $4,200, then the purchase manager will introduce the new product upgrade with new components

  C. Only if the average cost per product upgrade is $4,060, will the purchase manager introduce new product upgrades with new components

  D. If the average cost per new product upgrade is less than $180, then the purchase manager will introduce the new product upgrade with new components

  Correct Answer: C
