Question

A new school district superintendent was preparing to reallocate resources for physically impaired students and wanted to know if the schools in the district differed in the distribution of physically impaired students. Samples of 20 students from each of five schools were selected identifying 4 impaired students at School 1; 1 impaired at School 2; 6 at School 3; 3 at School 4; and 7 at School 5.

- Restate the question as a research hypothesis and a null hypothesis about the populations.
- Determine the characteristics of the comparison distribution.
- Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected.
- Determine your sample’s score on the comparison distribution.
- Decide whether to reject the null hypothesis.

Answer #1

Does presentation methodology improve retention for remembered
material? You know that the average number of concepts remembered
from a lecture is 20. You present information using a song to a
group of four participants. Here are their scores for the number of
concepts they remember from a lecture:
20, 21, 18, 29
Please conduct all steps of hypothesis testing and evaluate using a
one tailed test and alpha =.01. You must use all five steps in
hypothesis testing:
1. Restate...

Do students at various universities differ in how sociable they
are? Twenty-five students were randomly selected from each of three
universities in a region and were asked to report on the amount of
time they spent socializing each day with other students. The
result for University X was a mean of 7 hours and an estimated
population variance of 3 hours; for University Y, M=6, S2=2; and
for University Z, M=8, S2=1.5. What should you conclude? Use the
0.05 level....

In a school district, all sixth grade students take the same
standardized test. The superintendant of the school district takes
a random sample of 26 scores from all of the students who took the
test. She sees that the mean score is 121 with a standard deviation
of 14.3688. The superintendant wants to know if the standard
deviation has changed this year. Previously, the population
standard deviation was 24. Is there evidence that the standard
deviation of test scores has...

In a certain school district, it was observed that 26% of the
students in the element schools were classified as only children
(no siblings). However, in the special program for talented and
gifted children, 93 out of 313 students are only children. The
school district administrators want to know if the proportion of
only children in the special program is significantly different
from the proportion for the school district. Test at the α = 0.05
level of significance.

In a certain school district, it was observed that 25% of the
students in the element schools were classified as only children
(no siblings). However, in the special program for talented and
gifted children, 114 out of 386 students are only children. The
school district administrators want to know if the proportion of
only children in the special program is significantly different
from the proportion for the school district. Test at the α=0.05
level of significance.

In a certain school district, it was observed that 31% of the
students in the element schools were classified as only children
(no siblings). However, in the special program for talented and
gifted children, 78 out of 215 students are only children. The
school district administrators want to know if the proportion of
only children in the special program is significantly different
from the proportion for the school district. Test at the
α=0.01α=0.01 level of significance.

in a certain school district, it was observed that 28% of the
students in the element schools were classified as only children
(no siblings). However, in the special program for talented and

In a certain school district, it was observed that 33%
of the students in the element schools were classified as only
children (no siblings). However, in the special program for
talented and gifted children, 92 out of 246 students are only
children. The school district administrators want to know if
the proportion of only children in the special program is
significantly different from the proportion for the school
district. Test at the α=0.02α=0.02 level of
significance.
What is the hypothesized population proportion...
