b
Step-by-step explanation:
Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
Use this "1 mg = (1/1000000) kg = 10-6<span> kg = 0.000001 kg"</span>
Answer:
The probability that their mean life will be longer than 13 years = .9943 or 99.43%
Step-by-step explanation:
Given -
Mean 
= 15 years
Standard deviation 
= 3.7 years
Sample size ( n ) =22
Let 
be the mean life of manufacturing items
the probability that their mean life will be longer than 13 years =
= 
= 
= 
Using Z table
= 1 - .0057
= .9943
Answer: The correct answer is True.
When you are making coordinate proofs, you are using the value of the coordinates in your proof and your algebra work.
Often, the shapes are places along the axis, so at least one of the variables will be zero. This will allow you easy algebraic work because 0 times anything is o and 0 added to anything is itself.
