True average age of all students

A random sample of 64 students at a university showed an average age of 25 years and a sample standard deviation of 2 years. The 98% confidence interval for the true average age of all students in the university is:

a. 20.5 to 26.5

b. 24.4 to 25.6

c. 23.0 to 27.0

d. 20.0 to 30.0

Q : Corresponding triangle of forces

Draw a corresponding triangle of forces, indicating the sizes of the angles. Use the triangle of forces to find the magnitudes of the tension in the rope and the normal reaction from the ramp, to the nearest newton.

Q : Determine most probable macrostate

Use a computer to produce a table and graph, like those in this section, for two interacting two-state paramagnets, each containing 100 elementary magnetic dipoles. Take a "unit" of energy to be the amount needed to flip a single dipole from the "up"

A square loop of wire with sides of length 40 cm is in a uniform magnetic field perpendicular to its area. What is the magnitude and of the average emf induced in the loop?

Q : Average examination score of the population

A random sample of 49 statistics examinations was taken. The average score, in the sample, was 84 with a variance of 12.25. The 95% confidence interval for the average examination score of the population of the examinations is:

Q : Explain magnetic field is present in charge particle

If a charge particle move in a straight line and there no other forces on it except possibly from a magnetic field, can you say with certainty that no magnetic field is present? Explain.

Q : Determine rotational energy of a system

Molecules have additional degrees of freedom that atoms don't possess, namely, rotation and vibration. The energies associated with molecular rotation and vibration are quantized and photons can be emitted or absorbed by molecules making transitions

Q : Confidence interval for the population mean problem

A random sample of 144 observations has a mean of 20, a median of 21, and a mode of 22. The population standard deviation is known to equal 4.8. The 95.44% confidence interval for the population mean is:
