Problem #2
1) Conduct an independent-measures t-test using the following data set:
Group 1: 12 10 15 12 4 16 6 10 8
Group 2: 8 5 9 0 6 5 0 1

2) Determine the critical values (for an alpha of .05) that you should use to evaluate this t-score.
Please be clear with your steps on how you solved. How did you get each number and whether or not the hypothesis is rejected.

Conduct an independent samples t-test using the following
data:
A researcher is interested in testing how listening to music
affects exercise performance. She has one group listen to Tool and
another group listen to Jonas Brothers. The number of consecutive
reps on the bench before stopping was being measured. The following
data was collected:
Listening to Tool: 15, 18, 16, 19, 20
Listening to Jonas Brothers: 10, 9, 11, 13
a. What are the null and research
hypotheses?
b. Determine...

Describe the kind of data that are collected for an
independent-measures t test and the hypotheses that the test
evaluates. The key to helping formulate your explanation would be
to include the assumptions of this statistical model, the type of
sample used in this model, and a statement about the null
hypothesis.

12. Comparing ANOVA and the t test for an
independent-measures hypothesis test
Suzanne Zeedyk, a developmental psychologist at Dundee
University’s School of Psychology, conducted a pilot study in which
parents started a half-hour walk with their infants in a
parent-facing or an away-facing stroller and then switched to the
other type of stroller midway. Her results suggest that parents
talked less to the babies, the babies had higher heart rates, and
they were less likely to fall asleep in away-facing...

Assignment #3: Independent Samples T test Conduct an Independent
Samples T test to answer the questions based on the following
scenario. (Assume a non-directional research hypothesis (two-tailed
test) and a level of significance of .05) The superintendent who
collected data for Assignments 1 and 2, continued to examine the
district’s data. One question that concerned the superintendent’s
constituencies was the difference between the school performance
scores of the superintendent’s district and a neighboring district
that had similar demographic and socio-economic...
