The 99% confidence interval for the true mean is given by:
where:
is the sample mean = 69.7
is the standard deviation = 2.8
is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.
Therefore, the 99% confidence interval is:

Answer:
Properties of a Rectangular Prism : A rectangular prism has 8 vertices, 12 sides and 6 rectangular faces. All the opposite faces of a rectangular prism are equal.
Step-by-step explanation:
Answer: V = 4/3(3.14)(4.74)^3
That works out to 445.8650285
Rounded to 445.87 cubic inches.
Step-by-step explanation:
The basic formula for the volume of a sphere is
V = 4/3 πr³
Substitute a common value for π, 3.14 and the radius given.
When we use this formula, we find the volume is 445.87 in³
