ANSWER:
Here, NumPy and matplotlib are used. so, we need it import first:
CODE:
import numpy as np
import matplotlib.pyplot as plt
# Q1:
xv = np.random.uniform(20,80,5000)
# Q2:
xbar = np.average(xv)
# Q3:
# store average of each random dram in local var, and finally append that to xbarv
xbarv=[]
for i in range(300):
xv = np.random.uniform(20,80,5000)
xbar = np.average(xv)
xbarv.append(xbar)
# Q4:
# Bins size should be set comparable to data difference
# Using matploit lib to represent graph
plt.hist(xbarv, bins=np.arange(min(xbarv), max(xbarv)+0.09, 0.09))
plt.title("histogram")
plt.show()
# Q5:
# merge the above code
def f_myCLT(nrSamples,sampleSize,lower,upper):
xbarv=[]
for i in range(nrSamples):
xv = np.random.uniform(lower,upper,nrSamples)
xbar = np.average(xv)
xbarv.append(xbar)
return xbarv
# Q6:
# test code
xbarv = f_myCLT(400,10000,20,80)
plt.hist(xbarv, bins=np.arange(min(xbarv), max(xbarv)+0.1, 0.1))
plt.title("histogram")
plt.show()

R Programming codes for the above questions? In the notes there is a Central Limit Theorem example in which a sampling distribution of means is created using a for loop, and then this distribution is plotted. This distribution should look approximately like a normal distribution. However, not all statistics have normal sampling distributions. For this problem, you'll create a sampling distribution of standard deviations rather than means. 3. Using a for loop, draw 10,000 samples of size n-30 from a...
Law of Large Numbers, Central Limit Theorem, and Confidence Intervals 1. (15 points) In an exercise, your Professor generated random numbers in Excel. The mean is supposed to be 0.5 because the numbers are supposed to be spread at randonm between 0 and 1. I asked the software to generate samples of 100 random numbers repeatedly. Here are the sample means x for 50 samples of size 100: 0.532 0.450 0.481 0.508 0.510 0.530 0.4990.4610.5430.490 0.497 0.5520.473 0.425 0.4490.507 0.472...
2. According to central limit theory (CLT), for samples of size n is larger than the distribution of the sample means can be approximate to a normal distribution. The distribution of the sample gets better to be normal distribution as the sample size n_ (2 points) A. 30; increase. B. 50; increase. C. 30; decrease; D. 50 decrease;
Using R, Exercise 4 (CLT Simulation) For this exercise we will simulate from the exponential distribution. If a random variable X has an exponential distribution with rate parameter A, the pdf of X can be written for z 2 0 Also recall, (a) This exercise relies heavily on generating random observations. To make this reproducible we will set a seed for the randomization. Alter the following code to make birthday store your birthday in the format yyyymmdd. For example, William...
1. In this problem, you are going to numerically verify that the Central Limit Theorem is valid even when sampling from non-normal distributions. Suppose that a component has a probability of failure described by a Weibull distri- bution. Let X be the random variable that denotes time until failure; its probability density is: for a 2 0, and zero elsewhere. In this problem, assume k 1.5, 100 a) Simulate drawing a set of N-20 sample values, repeated over M 200...
Central Limit Theorem (CLT) 1. The CLT states: draw all possible samples of size _____________ from a population. The result will be the sampling distribution of the means will approach the ___________________- as the sample size, n, increases. 2. The CLT tells us we can make probability statements about the mean using the normal distribution even though we know nothing about the ______________-
