Question

#Draw three histograms based on simulation draws
(100,1000,10000)from a normal distribution with

#mean 2 and standard deviation 4.

#Label the median and the mean of your simulation results for each
histogram.

Please using Rstudio to complete it. And submit it in R format.

Answer #1

a) We generate 100 samples from normal distribution with mean 2 and SD 4.

b) We generate 1000 samples from normal distribution with mean 2 and SD 4.

b) We generate 10000 samples from normal distribution with mean 2 and SD 4.

Describe how you would draw and label a Normal distribution with
mean of 100 and standard deviation of 15.

Generate data of 600 random variable from normal distribution
with mean 8 and standard deviation 3 give it a name “MyData”
Calculate the following from MyData,
Mean, Variance, Standard deviation, minimum, Q1, Median, Q3,
Maximum.
Construct a histogram from MyData with title: Histogram of
MyData generated from Normal dist with mean= 8 and sd=3.
Construct a box plot from the generated data.

We will be using Google Sheets to simulate a normal
distribution with a mean of 650 and a standard deviation
of 8. Please note there are five parts to this question.
First, generate a random sample of 12 data points from a
normally distribution population (using the =norminv command in
Google Sheets). Create a histogram where the first bin starts at
628 and the width of each bin is 4. Save that histogram as an image
file and attach it...

Exhibit: Standard Normal Distribution.
Calculate the following for the standard normal distribution
using Excel. Round your solutions to 4 digits.
Hint: 1) it’s easier to understand the question if you
draw a picture for yourself; 2) recall that the standard normal
distribution has the mean of 0 and the standard deviation of 1.
A. Refer to the Exhibit Standard Normal Distribution.
Find the value of z such that the area to the right of
z is 0.0305.
B. Refer to...

1) Choose from the Following: Gaussian Distribution, Empirical
Rule, Standard Normal, Random Variable, Inverse Normal, Normal
Distribution, Approximation, Standardized, Left Skewed, or
Z-Score.
Same as the Normal Distribution
A statement whose reliability is based

Suppose the height of individuals in a population follow a
normal distribution with a mean (μ) of 66 inches and a standard
deviation (σ) of 4 inches.
a) Using the statistical software R, sample n individuals from
the distribution described above. For N=10,000 iterations, compute
the average height for n=5, n=15, n=50, n=100 individuals and plot
a histogram of the sampling distribution of the Z score (?̅−??/√?
)
b) Using the statistical software R, sample n individuals from
the distribution...

Q1-. A normal distribution has a mean of 15 and a standard
deviation of 2. Find the value that corresponds to the 75th
percentile. Round your answer to two decimal places.
Q2-.Tyrell's SAT math score was in the 64th percentile. If all
SAT math scores are normally distributed with a mean of 500 and a
standard deviation of 100, what is Tyrell's math score? Round your
answer to the nearest whole number.
Q3-.Find the z-score that cuts off an area...

i.Bias of Sample Mean Draw 20 samples from the normal
distribution N(5, 4). Compute the mean of your 20 samples. Report
the bias of the sample mean
ii. Variance of Sample Mean (Continue of problem i) To estimate
the variance of the sample mean, we need to draw many different
samples of size 20. Now, we draw 1000 times a sample of size 20.
Store all the 1000 sample means. Report the variance of the
estimated sample mean. Hint: To...

a.) Given a normal distribution with population standard
deviation of 21 and a mean of μ = 29. If a random sample
of size 62 is drawn, find P(29 ≤ x ≤ 31).
Round to three decimal places.
b.) Find the positive z value such that 89% of the
standard normal curve lies between –z and z. (Use
2 decimal places.)
c.) For a standard normal curve, find the area between
z = 0.28 and z = 1.95. (Use 4...

1. A distribution of values is normal with a mean of 70.8 and a
