An educational psychologist is interested in knowing whether the experience of attending preschool is related to subsequent sociability. She identifies two groups of first graders: those who had attended preschool and those who had not. Then each child is assigned a sociability score on the basis of observations made in the classroom and on the playground. Perform the 4 steps of hypothesis testing if using alpha is set at .05 for a two-tailed test.
The following sociability results are obtained:
Attended preschool Did not attend preschool
n1 = 12 n2 = 16
ΣX1 = 204 ΣX2 = 248
SS1 = 192 SS2 = 154

A psychologist is interested in knowing whether adults who were
bullied as children differ from the general population in terms of
their empathy for others. On a questionnaire designed to measure
empathy, the mean score for the general population is 80.82. Random
sampling of 76 scores obtained from individuals who were bullied
yielded a mean of 66.42 and a standard deviation of 22.87.
Suppose you want to calculate the 99% confidence interval.

A psychologist is interested in knowing whether adults who were
bullied as children differ from the general population in terms of
their empathy for others. On a questionnaire designed to measure

sampling of 25 scores obtained from individuals who were bullied
yielded a sample mean of 39.5 and a sample standard deviation of
6.6.

a) A psychologist is interested in whether or
not handedness is related to gender. Specifically, she wants to
know if the percentage left-handed men in the population is
different from the percentage of left-handed women. She collected
data on handedness for 200 men and 200 women. What type of
statistical test would be appropriate?
options: a) Chi-square goodness of fit test b) Independent
samples t-test c) Paired t-test d) Chi-square test of
independence
b) Nima investigated the relationship between

A clinical psychologist is interested in knowing if different
types of treatments have an effect on the
number of flashbacks per week experienced by Iraq War veterans. She
randomly selected a group of 24 veterans
with posttraumatic stress disorder (PTSD) from the local VA
hospital. Each person is randomly assigned to one of
three groups: Group 1 is a waiting list control group (no
treatment); Group 2 receives Eye Movement

Educational economists are trying to determine whether
preschool head-start programs are beneficial in improving reading
proficiency. To test the effect they conducted a lottery
with 100 parents of preschool kids who indicated that they wanted
to send their kids to a head-start program but couldn’t afford
it. The researchers randomly selected 36 students from
the 100 and gave them a voucher for preschool. All 36 of
these students attended a head-start program. After
attending head-start, and then 3 years of elementary school, all
100...

For the two large newspapers in your city, you are interested in
knowing whether there is a significant difference in the average
number of pages in each dedicated solely to advertising. You
randomly select 10 editions of newspaper A and 6 editions of
newspaper B (excluding weekend editions). The data follow. Use =
0.01 to test whether there is a significant difference in averages.
Assume the number of pages of advertising per edition is normally
distributed and the population variances...

Katie works in the film industry and was interested in knowing
whether people go to the movies more often in the summer than they
do in the winter (assume these data were collected prior to the
current pandemic). She collected data from ten people, asking each
of them to report how many movies they had gone to the previous
summer, and then followed up with them later that year to find out
how many movies they went to that winter....
