Answer:
Please see attached
Step-by-step explanation:
Answer:
a. There are 12 observations from the resulting data set.
b. This is an analytic study. It compares the flow rates through a solenoid valve based on three factors at four different levels.
Step-by-step explanation:
Observations of the dependence of flow rate
Factors Armature Spring Bobbin
Lengths Load Depth
Levels
Low 1 1 1
Moderate 1 1 1
High 1 1 1
Extreme 1 1 1
Total observations 4 4 4
Number of observations = 12
b) Whereas enumerative studies are statistical studies carried out to draw a conclusion on a process or a condition, analytic studies are statistical studies that compare two or more groups or sets of data to improve future performance. The focus of an analytic study is on the process rather than the condition. Enumerative studies tend to explain, evaluate, and describe the condition of the dataset.

Given, 18 pumps----2170 tonnes----10*7 hrs.
So, 16 pumps-------2170 tonnes----10*7*18/16 hrs.
And, 16 pumps-------1736 tonnes----10*7*(18/16)*(1736/2170)hrs. = 63 hrs.
So, no. of days req.= 63/9 = 7 days
The probability is 2/9 because there are 9 marbles and 2 marbles were pulled out. hope I helped XD
