A university administrator expects that 25% of students in a core course will receive an A. He looks at the grades assigned to 60 students. a. What are the expected value and the standard error for the proportion of students that receive an A? b. Use an appropriate normal transformation to calculate the probability that the percentage of students that receive an A is 20% or less. c. Use an appropriate normal transformation to calculate the probability that the proportion of students who receive an A is between 0.20 and 0.35. d. Use an appropriate normal transformation to calculate the probability that the proportion of students who receive an A is not between 0.20 and 0.30

A university found that 10% of students withdraw from a math
course. Assume 25 students are enrolled.
Write the prob. distribution function with the specific
parameters for this problem
Compute by hand (can use calculator but show some work) the pro
that exactly 2 withdraw.
Compute by hand (can use calculator but show some work) the
prob. that exactly 5 withdraw.
Construct the probability distribution table of class
withdrawals in Excel. This is a table of x and f(x).

A survey of undergraduate college students at a small university
was recently done by an administrator in charge of residential life
services. A random sample of 300 students was selected from each
class level (freshman, sophomore, junior, senior). Each student was
asked to complete and return a short questionnaire on quality of
campus residence. Some students returned the questionnaire, and
some didn't. This is summarized in the table below:

. The learning styles of students in a university biology course
were measured and the students were divided into two groups
depending on their propensity towards visual learning (style 1)
versustext-based learning (style 2). Severalteaching interventions
aimed at visual learners were introduced into the course and the
instructors scored the students as to whether or not they showed
learning gains compared to the usual text-based materials. The
results are given in the table below. Conduct a Chi-square analysis
to determine...

Suppose we know that at a University XYZ that 15% of students
receive an A in their introductory statistics class, 20% receive a
B, 30% receive a C, 10% receive a D, and the rest receive an F. For
comparison, a sample of 260 students at University ABC is taken and
20% received an A, 25% received a B, 25% received a C, 10% received
a D, and the remaining students failed the class. When testing (at
the 5% level...

A university dean is interested in determining the proportion of
students who receive some sort of financial aid. Rather than
examine the records for all students, the dean randomly selects 225
students and finds that 45 of them are receiving financial aid.
Using a 95% confidence interval, what is the upper limit of the
confidence interval to estimate the true proportion of students who
receive financial aid.

The University is trying to decide whether to implement a
mandatory remedial math course for students with low test scores
upon admissions. Historically, students with low admissions test
scores have failed their first math course 61% of the time. A
random sample of students with low scores is selected and assigned
to a remedial math course. These students are tracked and it is
found that 102 out of 175 of them still fail their first regular
math course.

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...
