Eldrick manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown
1 answer:
Answer:
Eldrick can use both of these samples to find the mean frequency of each duck.
Step-by-step explanation:
Given
See attachment for samples
Required
Determine which is true
Reading through the options, we can see that Eldrick needs to evaluate the mean frequency of both samples.
To do this, both samples have to be put into consideration in order to arrive at the right value.
<em>Considering the options, we can conclude that (a) is correct.</em>

Answer:
True
Step-by-step explanation:
A six sigma level has a lower and upper specification limits between and
. It means that the probability of finding no defects in a process is, considering 12 significant figures, for values symmetrically covered for standard deviations from the mean of a normal distribution:
For those with defects <em>operating at a 6 sigma level, </em>the probability is:
Similarly, for finding <em>no defects</em> in a 5 sigma level, we have:
.
The probability of defects is:
Well, the defects present in a six sigma level and a five sigma level are, respectively:
Then, comparing both fractions, we can confirm that a <em>6 sigma level is markedly different when it comes to the number of defects present:</em>
[1]
[2]
Comparing [1] and [2], a six sigma process has <em>2 defects per billion</em> opportunities, whereas a five sigma process has <em>600 defects per billion</em> opportunities.
