In Hamilton county, ohio, the mean number of days needed to sell a house is 86 days (cincinnati Multiple listing Service, april, 2012). data for the sale of 40 houses in a nearby county showed a sample mean of 80 days with a sample standard deviation of 20 days. We want to do a hypothesis test to determine whether the mean number of days until a house is sold is different than the Hamilton county mean of 86 days in the nearby county.
a) State the null and alternative hypotheses you would use.
b) Compute the test statistic.
c)With α = 0.05, what is your conclusion?

Assume the car expert requested estimates of the mean number of days to sell for the Domestic cars
6 Assume the car expert requested estimates of the mean number of days to sell for the Domestic cars with a margin of error of seven days and the mean number of days of Foreign cars with a margin of error of eight days. Using 98% confidence, how large should the sample sizes be for each?
7 Suppose a Domestic car has a list price of $30,000 and a Foreign car has a list price of $30,000. What is...

A researcher wishes to estimate the number of days it takes an
automobile dealer to sell a Nissan Sentra. A sample of 50 cars has
a mean time on the dealer’s lot of 70 days. Assume the standard
deviation for the population is 7.5 days
A) Find the best point estimate of the population mean.
___________(hint: no work needed)
B) Find the 95% confidence interval of the population mean.
Conclusion: We can say with 95% confidence that the population

The mean number of shopping trips per week in a county is 2.2.
In a particular neighborhood within the county, a survey based on
50 people reveals that the mean in the neighborhood is 1.85, with a
standard deviation of 1.2. Test the null hypothesis that the mean
in the neighborhood is no different from that in the county. State
the null and alternative hypotheses, find the test statistic,
compare it with the critical value, make a decision, and find...

. A researcher wishes to see if the mean number of days that a
basic, low-price, small automobile sits on a dealer’s lot is 29. A
sample of 30 automobile dealers has a mean of 30.1 days for this
type of automobile. At an alpha 0f 0.05, test the claim that the
meantime is greater than 29 days. The standard deviation (sigma) of
the population is 3.8 days.
a. Support the claim b. Do not support the claim

The mean number of sick days an employee takes per year is
believed to be about 10. Members of a personnel department do not
believe this figure. They randomly survey 8 employees. The number
of sick days they took for the past year are as follows: 11; 6; 13;
3; 11; 9; 8; 10. Let X = the number of sick days they took
for the past year. Should the personnel team believe that the mean
number is about 10?...
