Amy wishes to determine if the mean cost of new Volkswagen
vehicles is the same for the five Volkswagen dealerships in her
city. The same seven vehicles (year, make, and model) were priced
at the five dealerships.Complete the One-Way ANOVA table below
testing the null hypothesis of no difference in the true mean cost
for the five dealerships. Can you reject the null hypothesis? Carry
out the appropriate six step procedure using ?? = 0.05. [Hint:
Think of how RBD ANOVA relates to One-Way ANOVA.]

A local retail business wishes to determine if there is a
difference in the mean preferred indoor temperature between men and
women. Assume that the population standard deviations of preferred
temperatures are equal between men and women. Two independent
random samples are collected. Sample statistics of preferred
temperatures are reported in the table below.
Sample size Mean (in Celsius) Standard deviation
Men (Group 1) 25 22.5 1.2
Women (Group 2) 22 20.1 1.4

A marketing company wants to know the mean price of new vehicles
sold in an up-and‑coming area of town. Marketing strategists takes
a simple random sample of 756 cars, and find that the sample has a
mean of $27,400 and a standard deviation of $1300.
1. Assume that the population standard deviation is unknown.
What is the error of estimate for a 95% confidence interval?
2. Assume that the population standard deviation is known to be
$1500. What is the...

A manager wishes to determine whether the mean times required to
complete a certain task differ for the three levels of employee
training. He randomly selected 10 employees with each of the three
levels of training (Beginner, Intermediate and Advanced). Do the
data provide sufficient evidence to indicate that the mean times
required to complete a certain task differ for at least two of the
three levels of training? Carry our ANOVA test at α 0.05. The data
is summarized...

A manager wishes to determine whether the mean times
required to complete a certain task differ for two levels of
employee training. He randomly selected seven employees with each
of the two levels of training (Beginner and Advanced). Further, he
wants to know if the time (in minutes) is different for males and
females. The data is summarized in the table.

A researcher wants to determine if there is a significant
difference in the mean cost of a meal in the world's most expensive
restaurants. A survey of 100 people in the most expensive
restaurant in the world in Tokyo, Japan produced an average cost
per person of $277 and a standard deviation of $35. A survey of 100
people in the second most expensive restaurant located in Toronto,
Canada produced an average cost per person of $213 with a standard...

A pizza shop owner wishes to find the 95% confidence interval of
the true mean cost of a large plain pizza. How large should the
sample be if she wishes to be accurate to within $0.14 ? A previous
study showed that the standard deviation of the price was $0.40.
