Answer: The required interval is (0.679, 0.821).
Step-by-step explanation:
Since we have given that

So, the proportions would be

So, At 90% confidence interval, the z score value would be
z = 1.65
and the hypothesis are :

So, the 90% confidence interval would be

Hence, the required interval is (0.679, 0.821).
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> the number of open acres
y ----> the number of developed acres
we know that
-----> inequality A
----> inequality B
Remember that
if the number of open acres, x, can be no more than 1. then the number of open acres, x must be less than or equal to 1
Solve the system of equations by graphing
The solution is the shaded area (Note The number of acres cannot be a negative number)
The graph in the attached figure
Nearest hundred thousand: 100,000
Nearest ten thousand: 130,000
Nearest thousand: 127,000
The closest rounded amount to the actual attendance is the nearest thousand, 127,000.
Step-by-step explanation:
A leap year occurs every 4th year.
So, 1875 - 1700 = 175
Now let us divide 175 by 4

So, 43 leap years occur between the years 1700 and 1875.
