Submit the assignment in the Assignment 5 drop box.
Total points is 50 (Each question is 10 points).
Note: You can solve the questions manually or use Excel or
SPSS to solve the questions.

1.
A study by a bank compared the average savings of customers
who were depositors for three years or less with
those who had been depositors for more than three years. The
results of a sample are:
To test that the two groups of customers have equal savings
rates, what is the p-value for a two-tailed test?

2. 2.
A financial planner wants to compare the yield of income and
growth mutual funds. Fifty thousand
dollars is invested in each of a sample of 35 income and 40
growth funds. The mean increase for a
two-year period for the income funds is $900. For the growth
funds, the mean increase is $875.
Income funds have a sample standard deviation of $35; growth
funds have a sample standard
deviation of $45. Assume that the population standard
deviations are equal.
At the 0.05 significance level, is there a difference in the mean
yields of the two funds?
What is the computed value of the test statistic?
3.
Identify the design of each experiment below as paired samples
or independent samples. In each case

3. give the df.
a. Ten students compared the legibility of headlines. In one
condition the headlines were all
in CAPITALS. In the other condition the first letters were
capitalized. Each student
judged on a scale of 1-10. Five judged the all capitals headline;
five judged the first letter
only capitalized.
b. On the basis of Critical Reading SAT scores, each male was
matched with a female. Then
the math SAT scores were found and the mean for the 18 males
was compared to the mean
of the 18 females.
c. To control for socioeconomic status, this study used only
families with annual incomes in
the $40-50,000 a year range. Thirty-six fathers of one-year-olds
were compared. Half had
participated in the Lamaze method a year earlier when their
child was born and half had not.
A non-verbal behavior score was taken during a 10-minute
father-child session.
d. d. A comparison of 54 fathers to their 54 sons all of whom
were union members, showed
the older men had higher spatial ability scores.

4. 4.
A social psychologist wanted to determine whether attitudes of
men toward abortion were different in
rural and urban areas. He prepared a questionnaire and
administered it to a group of city dwellers and
a group of country dwellers. Each city man was matched with a
country man on age, income, and
education. High scores indicate positive attitudes toward
abortion. Here are the questionnaire scores.

a. What statistical method should be used and why?
b. Calculate a 95% confidence interval about the difference in

5. the two populations.
c. Use the CI to test the null hypothesis that rural and urban
men have identical attitudes toward
abortion.

Here is an experiment modeled after that of Triplett (1897), who
conducted the first social psychology
experiment.
Twenty-four 5th graders were given fishing reels. Twelve were
tested individually. The number of
yards of line reeled in 10 seconds was recorded for each. The
other group was tested together
under conditions of competition; the one who reeled the most
line got to keep the reel. The
following summary statistics were obtained.

Interactive Mindfulness Activity and Reflection (IMAR): The
Raisin Exercise
For this IMAR, you will need a few raisins; any color will do.
1. Place the raisins in front of you on a table or similar surface.
2. It is helpful to walk out of the room and re-enter since this
can foster a sense of newness or curiosity.
3. Approach the spot where you’d placed the tiny objects and
look at them as if for the very first time. Allow yourself to feel
a sense of wonder and interest while resisting the mind’s
tendency to label what you are seeing.
4. Take a few moments to pay careful attention to:
· The way they our item looks
· How it feels
· How your skin responds to its manipulation
· Its smell
· Its taste
If thoughts or judgments arise during your examination, that is
okay; simply notice that your mind veered and bring your
awareness back to your object with fresh eyes. You may find it
helpful to spend one minute on each of the five aspects noted
above.
It’s useful to repeat the exercise more than once. See if you can
maintain a sense of openness and curiosity throughout each
step.
Focusing on a single object such as a raisin is meant to bring
your mind to the present, to what is right in front of you. It also
allows for the practice of fostering curiosity and openness,

7. which are useful in suspending judgments and preconceptions.
It is nearly impossible to avoid practicing mindfulness when
you follow these instructions and take notice of what is in front
of you in the present moment.
Reflection:
Consider the following statement: By focusing on the raisin in
your hand and making a point to notice everything about it, you
are unlikely to be expending energy, time and attention on
worrying or ruminating about other parts of your life.
· Describe your experiences (good or bad) with the Raisin
Exercise.
· Did you notice your attention shifting away from worries or
ruminations about other parts of your life as you did this
activity?
· How did this activity affect your mood or emotional state?
(Consider how you may have felt before, during, and
immediately after completing the activity.)
· Management experts like Peter Senge and others suggest that
dialogue involves balancing inquiry and advocacy. With respect
to leadership of human service organizations, do you see the
mindfulness activity you just completed as relevant to this
statement? If so, in what way? If not, why not?
