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

Question 11

Which statement(s) are correct about the Regression shown here? (Note: There are 2 correct answers).

The dependent variable is the outside temperature

The relationship between outside temperature and number of customers per hour is a Linear Regression

The dashed lines indicate with 95% confidence where all of the process data should fall between

The dashed lines indicate with 95% confidence the estimate for the Quadratic Regression Line

The predicted number of customers per hour is close to 5 if the outside temperature is 10 deg C

Question 12

Review the analysis shown here. Which statements are true about the process? (Note: There are 3 correct answers).

The initial focus for this project would be to determine why the thicknesses are so frequently too low

The majority of the process is closer to the lower specification limit

This process is described with the Weibull Distribution

The process has more problems with Variation than Centering

The process follows a non-normal distribution with the given data

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.

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

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

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

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

Question 17

For the data set shown here which of these statements is/are true?

Hypothesis Testing of Means or Medians cannot be done since there are an unequal number of observations for the 3 samples

A Paired T-test would be applicable for comparing Grade B and Grade A since they follow each other in the data set

Grade A has the lowest sample Mean of the 3 samples

Grade A has a higher sample Mean than Grade B
