An instructor who taught two sections of engineering statistics last term, the first with 25 students and the second with 30, decided to assign a term project. After all projects had been turned in, the instructor randomly ordered them before grading. Consider the first 15 graded projects.
(a) What is the probability that exactly 13 of these are from
the second section? (Round your answer to four decimal
places.)
(b) What is the probability that exactly 9 of these are from the
first section? (Round your answer to four decimal
places.)
(c) What is the probability that at all 15 of these are from the
same section? (Round your answer to six decimal places.)
If you could please explain how to do it out on a calculator that would be much appreciated as the exam will ask us to solve this problem using a TI 84 plus CE.

An instructor who taught two sections of MTH132, with 20 and 30
students respectively. The instructor randomly select 15 students
for a field trip. 1. What is the chance that exactly 10 of them are
from the 2nd section?
2. What is the chance that at least 10 of them are from the 2nd
section?
3. What is the chance that at least 10 of them are from the same
section?

Two sections of a class in statistics were taught by two
different methods. Students’ scores on a standardized test are
shown in Table 5.12 . Do the results present evidence of a
difference in the effectiveness of the two methods? (Use α
= 0.05.)
Class A: 74, 97, 79, 88, 78, 93, 76, 75, 82, 86, 100, 94
Class B: 78, 92, 94, 78, 71, 85, 70, 79, 76, 93, 82, 69, 84

Statistics students believe that the mean score on a first
statistics test is 65. The instructor thinks that the mean score is
higher. She samples 10 statistics students and obtains the
scores:
Grades
73.5
68.4
65
65
63.9
68.4
64.3
66.5
61.9
69
Test grades are believed to be normally distributed.
Use a significance level of 5%.
State the standard error of the sample means: (Round
to four decimal places.)
State the test statistic: t=t= (Round to
four decimal places.)

...Statistics students believe the mean grade on the first exam
is 65. A statistics instructor thinks the mean grade is higher than
65. He samples ten statistics students and finds their mean grade
is 67 with a standard deviation of 3.1972 for the sample. Use the
Traditional Method and α = 0.05 to test the instructor’s claim. The
data are assumed to be from a normal distribution. ...

Your statistics instructor claims that 60 percent of
the students who take her Elementary Statistics class go through
life more enriched. For some reason that she can't quite figure out
, most people don't believe her. You decide to check this out on
your own. You randomly survey 64 of her past Elementary Statistics
students and find that 34 feel more enriched as a result of her
class. Now , what do you think? (Only using R-Lab)
