Answer:
a) P(79 <= P <= 81) = 0.9968
b) P( X > 81 ) = 0.0002
Step-by-step explanation:
mean value = 75 GPa
standard deviation = 1.7 GPa
<u>a) Determine P(79 <= P <= 81) </u>
given that : n = 25
attached below is the detailed solution
P(79 <= P <= 81) = 0.9968
<u>b) Determine how likely the sample mean diameter will exceed 81 </u>
given that n = 36
mean diameter = 81
P( X > 81 ) = 0.0002
Answer:
b1 = (2A/h) - b
Step-by-step explanation:
Follow these steps to solve:
A= h ( b1 + b2 ) / 2
2A = h (b1 + b2)
2A/h = b1 + b2
(2A/h) - b2 = b1
b1 = (2A/h) - b2
False. A research paper is based on facts, that's why you have to do research on it. If it was all your own thoughts, you could just write down whatever.
