hello your question is incomplete attached below is the complete question
answer : The population mean LDL level after six months is same for all four treatments
Step-by-step explanation:
A null hypothesis represents a no difference in the question. therefore the correct option is The population mean LDL level after six months is same for all four treatments

5:3. there are 5 balls, and 3 rackets
Answer:
It will take 12 hours
Step-by-step explanation:
Distance equals rate times time
d = rt
We know the distance and the rate
240 = 12 * t
Divide each side by 12
240/12 = 12t/12
20 = t
It will take 12 hours
Answer:
7949.13 feet
Step-by-step explanation:
We are given that,
Angle of depression from the spot to the group = 39°
Height of Grand Canyon = 5000 feet.
So, we will get the following figure of a right triangle.
<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>
We get, 
i.e. 
i.e. 
i.e. 
i.e. x = 7949.13 feet
Thus, the line of sight distance is 7949.13 feet.
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.
