A normal population has a mean of $61 and standard deviation of $13. You select random samples of nine. What is the probability that a sample mean is between $57 and $64

Answers

Answer 1

Based on the normal population mean and the standard deviation, the probability that a sample $57 and $64 is 0.5761.

How can the probability be found?

The probability that the mean is between $57 and $64 can be shown as:

P (57 < x < 64) = P ( ( lower limit - Upper limit) / Standard deviation / √ sample mean) < Z < P ( ( lower limit - Upper limit) / Standard deviation / √ sample mean)

Solving gives:

P (57 < x < 64) = P ( ( 57 - 61 ) / 13 / √ 9) < Z < ( ( 64 - 61 ) / 13 / √ 9)

= P( -0.92 < Z < 0.69)

Using the Z-table:

= P( Z < 0.69) - (P (Z < -0.92)

= 0.7549 - 0.1788

= 0.5761

In conclusion, the probability that a sample mean is between $64 and $57 is 0.5761.

The acceleration of the pendulum mass D is; r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j

What is Kinematics of particles?

Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.

From the sample problem, we can solve it using the (x, y, z) coordinate system to get;

r_c = x(t) i

r_d = [x(t) + l sin θ]i + l cos θ j

Finding the first derivative of r_d gives velocity as;

r'_d =  [x'(t) + lθ' cos θ]i - lθ' sin θ j

Taking the second derivative of r_d gives the acceleration as;

r"_d =  [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j

Assuming that everything else is equal, a U.S. government bond that matures 30 years from now most likely pays a higher interest rate than a U.S. government bond that matures 10 years from now. This is further explained below.

What is the interest rate?

Generally, The Federal Reserve raised its benchmark interest rate by 0.75 percentage points on Wednesday, bringing the total to a range of 2.25 percent to 2.5 percent. This is the second straight rise in interest rates by the Federal Reserve. Chair Jerome Powell has indicated that there will come a time when the Fed would begin to pause rises in order to evaluate the effect of those hikes.

In conclusion, When all other factors are considered, a United States government bond with a maturity date that is 30 years in the future will almost certainly pay a greater interest rate than a United States government bond with a maturity date that is 10 years in the future.
