Boys’ IST scores: 20, 20, 20, 21, 21, 20, 23, 21

In 2010, 76.3% of college students enrolled in an education
major were female. A sample of students enrolled in an education
major in 2019 consisted of 115 females and 70 males.
Would this data be sufficient at the 0.01 level of significance to
conclude that the percentage of females enrolled in an education
major decreased from the 76.3%?

8. I am interested in whether or not students who fail this
statistics course one semester do better on their tests
the second time they take the class. To examine this, I record the
test scores for a sample of 10 students who took the class last
semester and are repeating the class this semester. The test scores
for these 10 students are reported below for last semester and this
semester. Conduct the appropriate hypothesis test to determine
whether or...

Students enrolled in an introductory statistics course at a
university were asked to take a survey that indicated whether the
student’s learning style was more visual or verbal. Each student
received a numerical score ranging from -11 to +11. Negative scores
indicated a visual learner, and positive scores indicated a verbal
learner. The closer the score was to -11 or +11, the stronger the
student’s inclination toward that learning style. A score of 0
would indicate neutrality between visual or...

A researcher wants to determine whether high school students who
attend an SAT preparation course score significantly different on
the SAT than students who do not attend the preparation course. For
those who do not attend the course, the population mean is 1050 (μ
= 1050). The 16 students who attend the preparation course average
1150 on the SAT, with a sample standard deviationof 300. On the
basis of these data, can the researcher conclude that the
preparation course has...

A researcher is interested in examining whether there are
differences in students’ sense of safety across schools. She
selects three schools and surveys five students from each school.
The tab labeled Question 3 reflects the answers from this
survey—the higher the score, the safer the student feels. Is there
a difference between these schools in the students’ sense of
safety?
