Answer #1

In a large hospital, a nursing director selected a random sample
of 30 registered nurses and found that the mean of their ages was
30.2. The population standard deviation for the registered nurse
ages is 5.6. She selected a random sample of 40 nursing assistants
and found the mean of their ages was 31.7. The population standard
deviation of the ages for the assistants is 4.3. At the 1% level of
significance, test the claim that the mean age of...

Only 16% of registered voters voted in the last election. Will
voter participation decline for the upcoming election? Of the 347
randomly selected registered voters surveyed, 45 of them will vote
in the upcoming election. What can be concluded at the αα = 0.05
level of significance?
For this study, we should use Select an answer z-test for a
population proportion t-test for a population mean
The null and alternative hypotheses would be:

The average test score for the statistics course is 74%. A
professor wants to see if the average test score for students who
are given colored pens on the first day of class is higher. The
test scores for the 12 randomly selected students who were given
the colored pens are shown below. Assume that the distribution of
the population is normal.
81, 61, 86, 63, 74, 91, 62, 70, 80, 94, 70, 87

With the influx of new nurses, a hospital has decided install
the Continental time scale of 12 hour shifts versus the Regular 8
hour shifts to see if this change will improve job satisfaction, as
measured by a questionnaire that assess satisfaction or
dis-satisfaction. A higher score implies greater satisfaction.
Questionnaire scores of 18 randomly chosen nurses before and after
the implementation of these new working hours are shown in the
following table.
Job Satisfaction Index

Regular Hours...

A study was designed to compare the attitudes of two groups of
nursing students towards computers. Group 1 had previously taken a
statistical methods course that involved significant computer
interaction. Group 2 had taken a statistic methods course that did
not use computers. The students' attitudes were measured by
administering the Computer Anxiety Rating Scale (CARS). A random
sample of 6 nursing students from Group 1 resulted in a mean score
of 48.2 with a standard deviation of 3.6. A...

A random sample of high school seniors took a literacy test
before graduation. A comparison of scores for the test showed that
women scored significantly higher on average (p-value = 0.017) than
men on the literacy test. What does the p-value in this statement
tell us?
If there were actually no difference in the mean literacy scores
for all men and women at the high school, the probability of
observing a difference between the two group means as large or...
