Question

Suppose students ageas follow a skewed right distribution with a
mean of 25 years old and a standard deviation of 15 years. consider
the random sample of 100 students.

Determine the probability that the sample mean student age is
greater than 22 years?

Answer #1

Refer Standard normal table/Z-table to find the probability or
use excel formula "**=NORM.S.DIST(-2, TRUE)**" to find
the probability.

**The probability that the sample mean student age is
greater than 22 years is

Suppose students' ages follow a skewed right distribution with a
mean of 24 years old and a standard deviation of 5 years. If we
randomly sample 250 students, which of the following statements
about the sampling distribution of the sample mean age is
incorrect?
The shape of the sampling distribution is approximately
normal.
The mean of the sampling distribution is approximately 24 years
old.
The standard deviation of the sampling distribution is equal to
5 years.
All of the above...

Lifetimes of a certain brand of lightbulbs is known to follow a
right-skewed distribution with mean 24 months and standard
deviation 2 months. Let X̄ represent the sampling distribution of
the sample mean corresponding to a sample of size 1500 from this
distribution. We expect this sampling distribution to be...
Select one:
a. Approximately Normal with a mean of 24 months and a standard
deviation of 0.0013 months.
b. Right-skewed with a mean of approx. 24 months and a standard...

The ages of all college students follow a normal distribution
with a mean of 27 years and standard deviation of 4.4 years. Find
the probability that the mean age for a random sample of 36
students would be:
Between 25.5 and 28 years old
Less than 25.5 years old
Instructions:
Draw the normal curve and shade the area where applicable
Do not give calculator key strokes. (Give the formula used)
Circle your answer to the question.

Home prices in a certain community have a distribution that is
skewed right. The mean of the home prices is $498,000 with a
standard deviation of $25,200.
a. Suppose we take a random sample of 30 homes in this
community. What is the probability that the mean of this sample is
between $500,000 and $510,000?
b. Suppose we take a random sample of 10 homes in this
community. Can we find the approximate probability that the mean of
the sample...

The times that college students spend studying per week have a
distribution skewed to the right with a mean of 8.7 hours and a
standard deviation of 2.2 hours. Find the probability that the mean
time spent studying per week for a random sample of 45 college
students would be a. between 8.3 and 8.9 hours.

The population distribution of college Student debt, as of May,
2019, is heavily skewed to the right with a mean debt of $30,000
and a standard deviation of $7510.
Explain why it is not possible to determine the probability
that a randomly selected college student in your area, has a debt
that’s less than $28,000
Determine the probability that a random sample of 30 college
students will have a mean debt of less than $28,000. Be sure to use
the...

The
lifespan of laptop computers is skewed right with a mean of 5.5
years and a standard deviation of 3.5 years.
If simple random samples of 49 laptop computers are randomly
selected, then what do we know about the distribution of the sample
means? Choose one of the answers below:
A. the distribution is normal
B. the distribution is approximately normal
C. the distribution is exponential

Suppose a population of FORMER high school graduates in
Wisconsin is normally distributed with a mean age of 24 years and a
standard deviation is 1.25 years. Consider a sample size of 100
high school graduates. Find the probability that the sample mean
age of these students greater than 24.3 years.

The distribution of the commute times for the employees at a
large company has mean 22.4 minutes and standard deviation 6.8
minutes. A random sample of n employees will be selected and their
commute times will be recorded. What is true about the sampling
distribution of the sample mean as n increases from 2 to 10 ? The
mean increases, and the variance increases. A The mean increases,
and the variance decreases.
B The mean does not change, and the...

The weight of all 20-year-old men is a variable that has a
distribution that is skewed to the right,and the mean weight of
this population, μ, is 70 kilograms. The population standard
deviation, σ,is 10 kilograms (http://www.kidsgrowth.com). Suppose
we take a random sample of 75 20-year-old men and record the weight
of each.
What value should we expect for the mean weight of this sample?
Why?
Of course, the actual sample mean will not be exactly equal to
the value...
