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 $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
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
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
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

Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more
Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more
If the Adv is increased from the low level to the high level, the response rate increases
If the Adv is increased from the low level to the high level, the response rate increases
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
