It should be tested whether a cube is fair or not. This tells how many times the number 1 appears.

With a sample, a dice is thrown 720 times and it showed number one 95 times. The null hypothesis is Ho:p =1/6. Probability of error is specified α=0.05

a)Approximate the binomial distribution according to Moivre-Laplace by normal distribution (without correction ).

b) derive a formula for the rejected area or accepted area.

The U.S government wants to determine whether immigrants should be tested for a contagious disease, and it is planning to base this decision on financial considerations. Assume that each immigrants who is allowed to enter the United States and has the disease costs the country $100,000. Also, assume that each immigrants who is allowed to enter the United States and does not have the disease will contribute $10,000 to the national economy. Finally, assume that x percent of all potential...

An ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment. Compute the probability of each of the following events. Event A : The sum is greater than 5 . Event B: The sum is an...

The electron configuration of an atom tells us how many electrons are in each orbital. For example, helium has two electrons in the 1s orbital. Therefore the electron configuration of He is 1s2 part a: What is the ground-state electron configuration of a neutral atom of nickel? Express your answer in condensed form, in order of increasing orbital energy. For example, [He]2s22p2 would be entered as [He]2s^22p^2 . part b: What is the ground-state electron configuration of the oxide ion...
