1 answer:
<h2>Hello!</h2>
The answer is:
The correct option, is the second option:
b || c ( b and c are parallel).
<h2>Why?</h2>To solve the problem, let's remember the following relationship:
If:
and
Then:
So, from the statement we know that a and b are parallel (a || b), so, if a and c are parallel ( a || c) it means that b and c are parallel ( b || c).
Hence, the correct option is:
The second option, b || c ( b and c are parallel)

Answer:
Prof B and Prof D
Step-by-step explanation:
Step-by-step explanation:
From the question we are told that
Sample size 100
Instructor Number of Failures
Prof. A 13
Prof. B 0
Prof. C 11
Prof. D 16
Confidence level= 0.95
From Z table
Z=1.96
Generally proportion for failure is mathematically given as
For Prof A
For Prof B
For Prof C
For Prof D
Generally the average proportional failure is mathematically given as
Therefore having this we calculate for the control limits
Generally the upper control limit UCl is mathematically given as
Upper control limits:
Generally the upper control limit UCl is mathematically given as
Lower limit control limits:
Therefore the Range is 0.0412 to 0.1588
Given the range 0.0412 to 0.1588 Prof B and Prof D are outside the Range making them the correct options
