Answer:
The sampling distribution is, p = center = 0.043
The standard deviation of the sample, s = 6.0015×10⁻⁴
The shape is normal
Step-by-step explanation:
Here we have the standard deviation of a sample proportion, given by the following relation;
The center = p = 4.3% or 0.043
The shape is found by the value of n×p hence;
114250 × 0.043 = 4912.75 > 10 and
n(1 - p) = 114250 × (1 - 0.043) = 109337.25 also > 10 hence the shape is normal.
Answer:
The Riemann Sum for with n = 4 using midpoints is about 24.328125.
Step-by-step explanation:
We want to find the Riemann Sum for with n = 4 using midpoints.
The Midpoint Sum uses the midpoints of a sub-interval:
where
We know that a = 4, b = 5, n = 4.
Therefore,
Divide the interval [4, 5] into n = 4 sub-intervals of length
Now, we just evaluate the function at the midpoints:
Finally, use the Midpoint Sum formula
This is the sketch of the function and the approximating rectangles.
