A psychologist is interested in the relationship between color of food and appetite. To explore this relationship, the researcher bakes small coockies with icing of one of three different colors (green, red or blue). The researcher offers cookies to subjects while they are performing a boring task. Each subject is run individually under the same conditions, except for the color of the icing on the cookies that are available. Six subjects are randomly assigned to each color. The number of cookies consumed by each subject during the 30-minute session is shown in table below.
a. Calculate the F statistic: ***PLEASE show handwritten work for calculating SSbetween.***
b. Find the critical F(a = .01)
c. Present your results in the form of a summary table

A psychologist was particularly interested in the relationship
between hypnosis on memory. To test this she exposed 10 subjects to
a list of 40 nonsense words. She then hypnotized each subject and
asked them to recall as many words from the list as was possible.
The mean of these responses is 22 and the standard deviation is
5.9.
LV remembered 0 words. What is their z score?
SI remembered 21 words. What is their T score?

A researcher is interested in the relationship between
concussions and short-term memory loss. To explore this
relationship, the researcher collects data on the number of
concussions and number of words recalled on a memory test.
Assume SP = -34
SSconcussions =
58 SSnumber of words
recalled = 27
Interpret the Pearson correlation coefficient between
concussions and number of words recalled in terms of the strength
and direction of the relationship:

A psychologist is interested in the relationship between
intelligence and academic motivation. She recruits eight
participants for a study. Each participant completes an
intelligence test and a measure of academic motivation. Scores for
the eight participants are in the table below. Use intelligence
scores to predict motivation scores with regression analysis by
hand.

A researcher wanted to examine if there is a relationship
between color preference (i.e., favorite color: red, yellow, green
or blue) and personality type (i.e., extrovert or introvert). He
selected a sample of n = 200 participants; each participant took a
personality test and identified the favorite color. The collected
data are shown in the table below.
Do the data indicate a significant relationship between
personality type and color preference? Test with p <
.01.

A social psychologist is interest in whether there is a
relationship between cohabitation before marriage and divorce. A
random sample of 150 couples that were married in the past 10 years
in a Midwestern city were asked if they lived together before
getting married and if their marriage was still intact. The
following results were obtained. Using α=0.05, what do you
conclude?
Divorced
Still Married
58
42
Cohabitated before marriage

32
Did not cohabit before marriage

A psychologist conducted an experiment analysing the
relationship between student scores in an exam and the amount of
attention they paid in class. The latter was measured using a type
of brain monitor. The Psychologist believed that scores would
increase by 1 for every two unit increase in attention. The data
are listed in the excel spreadsheet.
Estimate a linear regression between the score (Y) and the
measure of attention(X).
(a) Write out the equation for Y in the form...
