Answer:
The standard error is 11.
Step-by-step explanation:
Given : If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4.
To find : The standard error ?
Solution :
The standard error formula is
Where, 
is the standard deviation of a normally distributed population
n=4 is the sample size
Substitute the value,
Therefore, the standard error is 11.
Here we are given the specific equation of:
amount of eroded soil = 0.4 + 1.3 x
where x is the flow rate
A linear equation has a general formula in the form of:
y = m x + b
where m is the slope and b is the y intercept of the equation
If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:
m = 0.4
b = 1.3
Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.
Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.
Answer:
positive, but we cannot say what the exact value is
Answer:
16/55
Step-by-step explanation:
If you add all the animals together then put it in fraction form you have 16/55
Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
