Advanced Placement (AP) Middle School

Multiple-choice questions on Advanced Placement exams have five options: A, B, C, D, and E.
A random sample of the correct choice on 400 multiple-choice questions on a variety of AP exams shows that B was the most common correct choice, with 90 of the 400 questions having B as the answer.

Does this provide evidence that B is more likely than 20% to be the correct choice?

a. Define the parameter, state hypotheses, and calculate the sample statistic.

b. Is a Normal distribution appropriate for this test, based on the values of n and Po? Explain.

c. Calculate the standard error and z-test statistic, assuming a Normal distribution is appropriate.

d. Find the p-value and draw a Normal curve with appropriate shaded region. You may give either a precise p-value from Stat key or bounds on a p-value from Table A.

e. State the conclusion of the test in context f. Find a 95% confidence interval for the proportion of questions on all AP exams having B as the correct choice using the normal distribution and the formula for standard error. Show your calculations

Think about the physical properties of the Sun, planets, and moons.
Using the word bank below to compare and contrast the Sun, the planets and moons. Include differences and similarities in size, composition, and location.

Word Bank:
solid, rocky, gas, spherical, color, orbit, revolution

Answers

The sun is very large in size and has lots of gasses on it while plants orbit the sun and are solid with many different shapes, colors, and sizes. Moons are smaller in size and are rocky and the shapes of them aren’t always spherical in shape. But moons do tend to have a revolution around planets, so do planets with the sun. But planets and moons do have simulates. For example, they do come in spherical shapes, orbit, are solid, rocky, and come in different colors, so do suns. The difference is that the sun is pretty the main thing that other smaller objects are orbiting and are larger than planets and moons.
The moon orbits the earth and when the earth orbits the sun that is called revolution
