  A. True
  B. False
  A. True

• Question 283:

  When conducting a Hypothesis Test using Continuous Data the proper sample size is influenced only by the extent to which we need to assess a Difference to be detected but not the inherent variation in the process.

  A. True

• Question 284:

  Two samples are drawn from two normal types of population. Which of the following test statistics can be used to show that the two types of population have the same mean while both have the same variance?

  A. F test
  B. Two sample pooled t-test

• Question 285:

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

• Question 286:

  Sally and Sara sell flower pots at their garage sale. Martha motivates Rose mentioning that they will sell a minimum of 16 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 15.2 pots per day were sold with a Standard Deviation of 0.6 pots.

  What is the Z value for this sales process?

  A. 0.67
  B. 1.13
  C. 1.33
  D. 2.66
  C. 1.33

• Question 287:

  Identify the incorrect statement.

  A. Parametric method uses the normality assumption
  B. Non parametric method does not use any normality assumptions
  C. Non parametric test results are more robust against violation of assumptions
  D. Non parametric tests provide greater power than parametric tests with equal sample sizes when assumptions are met
  B. Non parametric method does not use any normality assumptions

• Question 288:

  What conclusion is most correct about the Experimental Design shown here with the response in the far right column?

  

  A. No factor has enough statistical confidence greater than 95% to have an impact on the response rate
  B. Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more
  C. If the Adv is increased from the low level to the high level, the response rate increases
  D. The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate
  E. This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output
  D. The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate

  B. Standard Deviation
