Compare your sample estimate to the current mean gas in the U.S.
- What is the mean price of gasoline in the U.S.? You might try reading the graph on this GasBuddy website.
- Set up a null and alternative hypothesis to see if your sample for Dayton is enough to prove that the population mean price in Dayton is different than the mean price in the U.S. Test the hypotheses. Show your work.
- Using a significance level of 0.05, what is your conclusion?
You will need to show all your work, step-by-step, and write a final summary of the results and what you learned by doing this activity.
The mean price of gas in US is 2.22
The mean in Dayton is 2.217 SD is .070711 n is 30
The mean in Ohio is 2.21 SD is .0707 n is 5

Compare your sample estimate to the current mean gas in the
State of Ohio. Find the mean price of gasoline in the State of
Ohio. You might try this GasBuddy website. Set up a null and
alternative hypothesis to see if your sample for Dayton is enough
to prove that the population mean gasoline price in Dayton is
different than the mean price in Ohio. Test the hypotheses. Show
your work. Using a significance level of 0.05, what is your...

d. Obtain a beta estimate for your company. What does it mean?
Examine and compare the annual total returns and average return of
your stock with that of the S&P500’s returns. Did it follow the
Beta estimate? It would be helpful to illustrate the returns of the
company’s stock and the market. in general how would we compare
beta and returns? what would we say if returns higher or lower than
the s&p 500?

1)
what is the difference between sample estimate and population
parameter? if the sample mean of GRE test scores distribution was
90 and variance equivelent to 225 what can you say about the
population distribution?
2)
if the mean score of class of 20 students in Marketing is 80 and
variance is 256. calculate the coefficient of variation and provide
an interpretation of the results.

A random sample of 20 observations is used to estimate the
population mean. The sample mean and the sample standard deviation
are calculated as 162.5 and 22.60, respectively. Assume that the
population is normally distributed.
a. Construct the 99% confidence interval for the
population mean. (Round intermediate calculations to at
least 4 decimal places. Round "t" value to 3 decimal
places and final answers to 2 decimal places.)
b. Construct the 95% confidence interval for
the population mean. (Round intermediate...

A random sample of 29 observations is used to estimate the
population mean. The sample mean and the sample standard deviation
are calculated as 130.2 and 29.60, respectively. Assume that the
population is normally distributed
Construct the 95% confidence interval for the population
mean.
Construct the 99% confidence interval for the population
mean
Use your answers to discuss the impact of the confidence level
on the width of the interval.
As the confidence level increases, the interval becomes
wider.

A random sample of 27 observations is used to estimate the
population mean. The sample mean and the sample standard deviation
are calculated as 113.9 and 20.40, respectively. Assume that the
population is normally distributed. [You may find it useful
to reference the t table.]
a. Construct the 90% confidence interval for the
population mean. (Round intermediate calculations to at
least 4 decimal places. Round "t" value to 3 decimal
places and final answers to 2 decimal places.)
b. Construct...

Sample statistics, such as the sample mean or the sample
proportion, can be used to estimate a population parameter (such as
the population mean or the population proportion). For example, you
can estimate the true mean weight of all newborn babies in the
entire world by collecting a sample and using that sample to
generate a 95% confidence interval.
Because the sample is typically a relatively small portion of
the entire population, errors will have to be considered. Using a...

what does it mean if your sample mean is greater/or
less than your population mean? obviously I have to reject the null
for both circumstances but is there anything I can conclude about
the population?
