A college administrator is interested in knowing whether
a 3-week math mini-course affects a student's grade. Twenty
students are randomly selected and given a math test. These
students then attend the mini-course and are retested. Assume the
paired data come from a normal population for which the mean
difference is 0 Compute the value of the t-test statistic and
p-value for the paired data. At the 1% significance level,
determine whether the mini-course actually improves a student's
score.

Please note that for all problems in this course, the
standard cut-off (alpha) for a test of significance will be .05,
and you always report the exact power unless SPSS output states
p=.000 (you’d report p<.001). Also, remember when
hand-calculating, always use TWO decimal places so that deductions
in grading won’t be due to rounding differences.

perception skills of 32 deaf children: 16 subjects with at least
one cochlear implant (CI) and 16 subjects (with hearing loss)
without an implant. (CI subjects were implanted at 13 or 14 months
of age. So, no subjects had CIs at the time of the first data
collection.)...

from a grade perspective. On our moodle page you will find a link
to a second word document titled “300 Grades”. This data sheet
contains both the alphanumeric grade (page 1) and the numerical
equivalent (page 2) for every...
