Answer:
{r|r>0}
Step-by-step explanation:
Pressure is the amount of force exerted on a surface per unit area, P=F/A.
The pressure, in atmospheres (atms), of a liquid on the circular base of a bucket is represented by the composite function PoA(r), where P(A) = 375 / A and A (r) = pi r²
We know that the domain is the set of input values.
Pressure,
At r = 0, it becomes not defined.
It means that r can be any value that is greater than 0. Hence, the correct option is (c). i.e. {r|r>0}
Answer:
The 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).
Step-by-step explanation:
The confidence interval for difference in population proportion formula is,
The given information is:
n₁ = 11508
X₁ = 921
n₂ = 4967
X₂ = 452.
Compute the sample proportion values as follows:
The critical value of <em>z</em> for 95% confidence interval is:
*Use the standard normal table.
Compute the 95% confidence interval for difference between proportions as follows:
Thus, the 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).
