2) Suppose I use a random numbers table to randomly choose 900 numbers between 0 and 100. In this particular sample, the mean of the 900 numbers is 50 and the standard deviation is 30.

a)Approximately, what proportion of the 900 numbers should fall between 20 and 80 (inclusive)?

b)Suppose each student in Static (class size = 140) repeats the experiment described above and computes the mean of his or her 900 numbers. Based on the information given above, estimate the standard error of those 140 means.

c) Approximately, what proportion of those means should fall between 20 and 80?

Thank you.

1. A random number generator claims to randomly choose real numbers between 0 and 3000. (a) If this is true, what kind of distribution would the randomly chosen numbers have? (b) What would be the mean of this distribution? (c) What would be the standard deviation of this distribution? (d) Say we take a sample of 65 generated numbers and obtain a sample mean of 1552. What do we know about the sampling distribution of the sample mean and how...

Player 1 and Player 2 choose and integer between 0 and 100 (including 0 and 100). Their choice is made simultaneously and independently. Suppose Player 1 chooses x and Player 2 chooses y. If x < y Player 1 obtains x and Player 2 obtains zero. Similarly, if y < x Player 2 obtains y and Player 1 obtains zero. If x = y then each one obtains x/2 = y/2. Find all pure strategy Nash equilibrium in this game.

1.) Generate an array of 10 random numbers between 1 - 100 2.) Copy the array to a temp array 3.) Call each of the methods to sort (bubble, selection, insertion, quick, merge), passing it the array 4.) In-between the calls, you are going to refresh the array to the original numbers. 5.) Inside of each sorting method, you are going to obtain the nanoseconds time, before and after the method Subtract the before time from the after time to...

Design a modular program that accepts as input 20 numbers between 0 and 100 (including 0 and 100). The program should store the numbers in an array and then display the following information: The lowest number in the array The highest number in the array The total of the numbers in the array The average of the numbers in the array Your program should consist of the following: Module main. Accepts input of numbers and assigns them to an array....

Write an Arduino code that does the following. Generate 50 random numbers between the numbers 100 and 300. Pick a number at random out of these 50 random variables. a. Determine the probability of the chosen number being greater than 200. This may be achieved by counting the numbers that are greater than 200 and dividing the count by 50. Make sure you, i.Formulate the appropriate if-conditions to check for a number being greater than 200 ii. Use a for-loop...

Using only real numbers between 0 and 100, inclusive, show the set of three numbers whose product is 64 and whose sum is minimal is give by {4, 4, 4}. (a) When is an absolute minimum or maximum guaranteed? (b) State the steps to find an absolute minimum and maximum. (c) Is the space closed and bounded? Explain. (d) Use Lagrange Multipliers to find the minimum and maximum please label and write neatly.

how would you use randomly generated numbers to find 30 random numbers from 1 to 500?
