Answer:
im here for the points sorry
Step-by-step explanation:
Answer:

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.
Step-by-step explanation:
For this case we have that the sample size is n =6
The sample man is defined as :

And we want a normal distribution for the sample mean

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.
So for this case we need to satisfy the following condition:

Because if we find the parameters we got:


And the deviation would be:

And we satisfy the condition:

Answer:
x=4
x=17.9
Step-by-step explanation:
For the first diagram.
cos(45°)=x/4√2
x=4√2cos(45°)
x=4
For the second diagram
tan(38°)=14/x
0.781=14/x
x=14/0.781=17.9
Answer:
Step-by-step explanation:
Abx = cy
We want to get rid of 'ab', and it is being multiplied to 'x', so we divide it to both sides.
x = (cy)/(ab)
