Honor Section – Project

Math 227-Honor Section Last name, First name:________________,____________

Ask at least 70 female and 70 male students the following 5 questions: ______________/10 pts.

1. What is your age?
2. What is your GPA?
3. Are you going to transfer to a university?
4. How many hours a week they study for their course?

Here are the example of the collecting data:

# of Female student	Age	GPA	Transfer	# of hour
1	23	3.3	Yes	10
2	19	3.6	No	5
3	24	1.7	Yes	6

# of Male student	Age	GPA	Transfer	# of hour
1	22	3.1	Yes	7
2	27	2.8	yes	4
3	25	2.0	no	9

(Attention: Keep your data for the next project)

From age data for both groups, find:

1. The average.
2. The median.
3. The standard deviation
4. The variance.
5. The range of usual.
6. The acceptable range
7. The percentile of the age of 20.
8. Find P47
9. Find the 5 number summary.
10. Construct the boxplot
11. Find outlier(s) if any
12. Construct the steam and leaf plot.
13. Construct the frequency table with at least 4 class width.
14. Construct the histogram.
15. Construct pie chart.
16. Construct Frequency Polygon.
17. Construct Ogive.
18. How many percent (probability) of students (including female and female students) are going to transfer?
19. Find the probability of students who are going to transfer.
20. Find the probability of students who are not going to transfer.
21. Find the probability of selecting a student who is a female or is going to transfer.
22. At a 0.05 significance level test the claim that the average GPA of LACC students (including female and male) is less than 3.0.
23. At a 0.05 significance level, can you reject the claim that more than 70% of LACC students is going to transfer to a university?
24. Construct a 95% confidence interval estimate of the average GPA of LACC students.
25. How many college students must be randomly selected to estimate the mean GPA of college students in LACC? We want 99% confidence that the sample mean is within 0.3 points of the population mean, and the population standard deviation is 0.5.
26. a) At a significance level, test the claim that the LACC female student’s average GPA is greater than the LACC male students’ average GPA.
27. a) At a significance level, test the claim that the percent of transferring to a university is the same for both female and male students.

From # of studying hour for both female and male students:

18. Find the range of usual

From the Transfer data:

b) Construct the 95% significant difference between the two means.

b) Construct the 95% significant different between the two proportions.
