Question

**A sample of 165 Lancaster University (LU) undergraduates
who obtain their degree have a mean age of 24.4 years and a
standard deviation of 1.6 years. Combinations of 165 Lancaster
University (LU) undergraduates and 230 University of Abertay Dundee
(UAD) undergraduates have a mean age of 24.8 years and standard
deviation of 2.2 years. Find the mean and standard deviation for
the 230 university of Abertay Dundee (UAD)
undergraduates.**

Answer #1

Let be the mean age and Sx be the standard deviation of Lancaster University ( LU ).

= 24.4 , Sx = 1.6 , n1 = 165

Let be the mean age and Sy be the standard deviation of Abertay Dundee University ( UAD).

n2 = 230

We are given , + = 24.8 and = 2.2

= 24.8 - 24.4

**
= 0.4**

=

Sy =

Sy =

**Sy = 33.3113**

**Therefore for the 230 university of Abertay Dundee (UAD)
undergraduates Mean age
= 0.4 and standard deviation Sy = 33.3113**

Test the claim that the mean age of the population in Sin City
is less than 26 years. Sample data (assumed to be Normal) are
summarized as n=25, average=24.4 years and standard deviation=9.2
years. Use a significance level of 0.01.

A study was conducted using undergraduates at a rural university
who volunteered to participate in the research as partial
fulfillment of a course requirement. One of the items studied was
the amount of alcohol consumed (in drinks) in any one day for the
past month. Administrators want to know if there are differences in
alcohol consumption between freshmen and juniors. Based on the
information in the table below, what can be concluded with α =
0.05?
freshmen
juniors

3. Find the T value for a sample of 25 individuals who have a
sample mean of x̅ = 34, sample standard deviation of Sx = 4
relative to a population with a mean of μ = 38. Is this sample
significantly different (using a 2 tailed test with alpha set at
.05) from the sample with a mean of μ = 38?

1. In a sample of 64 Pasadena residents the mean age was 57.8
years. From the census it's known that the age has a standard
deviation of 6.5 years. Find a 90% confidence interval for the
population mean age. (Note: CL=0.90)

A group of university students are interested in comparing the
average age of cars owned by students and the average age of cars
owned by faculty. They randomly selected 25 cars that are own by
students and 20 cars that are owned by faculty. The average age and
standard deviation obtained from the students’ cars are 6.78 years
and 5.21 years, respectively. The sample of faculty cars produced a
mean and a standard deviation of 5.86 years, and 2.72.

A national study of people who purchase cars found the mean age
of a car buyer to be 48 and the population standard deviation 4
years. Your dealership decides to see if your customers fit this
same pattern. A sample of 80 customers found the mean to be 46
years of age. Are your customers younger than the national average
at the .005 level of significance? Use the five-step procedure to
answer the question and include the p-value.

A random sample of 16 students selected from the student body of
a large university had an average age of 25 years and a standard
deviation of 2 years. We want to determine if the average age of
all the students at the university is less than equal to or greater
than 24. Assume the distribution of the population of ages is
normal. Using α = .05, it can be concluded that the population mean
age is
not different than...

The president of a university claimed that the entering class
this year appeared to have a mean SAT score lower than previous
years. He took a sample of 20 of this year's entering students and
found that their mean SAT score is 1,501 with a standard deviation
of 53. The university's record indicates that the mean SAT score
for entering students from previous years is 1,520. He wants to
find out if his claim is supported by the evidence at...

A random sample of 16 students selected from the student body of
a large university had an average age of 25 years and a standard
deviation of 2 years. We want to determine if the average age of
all the students at the university is significantly more than 24.
Assume the distribution of the population of ages is
normal. At 95% confidence, it can be concluded that the
mean age is
a.
significantly different from 24
b.
not significantly different from...

1.) A sample of 125 campus students who responded to a
questionnaire had a mean age of 22.0 and a standard deviation of
5.0. The mean hypothesized population age for all campus students
is 25.0.
a) Set up the hypothesis (one sample t test) for
these data at the 95% confidence level. Be sure to include the null
hypothesis and alternative hypothesis in your response.
b) Compute the t test statistic for these data.
c) Are you able to reject the...
