A study of undergraduate computer science students examined changes in major after the first year. The study examined the fates of 256 students who enrolled as first-year students in the same fall semester. The students were classified according to gender and their declared major at the beginning of the second year. The students studied were enrolled at a large Midwestern university several years ago. Discuss how you would conduct a similar study at a college or university of your choice...

1. A study is conducted among first year undergraduate students in a US College of Nursing. From a list of these students, every 10th student is selected for an interview. Which of the following sampling strategies is being used? a) Simple random sampling b) Systematic sampling c) Stratified random sampling d) Cluster sampling 2. A study is conducted among first year nursing students in a US College of Nursing. Students are first grouped according to the state in which they...
A college campus wide survey indicates that 85% of the University Park 4th year undergraduate students live within a 3-mile radius of the campus. 1.) You are working with the campus survey team, and learn that there was a low response rate. In order to ensure the accuracy of that survey result, how many surveys would you need to collect in total in order to obtain a margin of error of +/- 3% with 98.122% confidence?
15 Connect Research at the University of Toledo nicates that 50% of students change ther maior area of 4 study after ter first year it a program A random sample of 100 students in the College of Business revealed that 48 had changed their major area of study after thei this program? Test at the 0.05 level of significance What is the decision nule? (Negative amount should be indiceted by a minus sign Round your answer to 2 decimal first...
A study compared the VCE ENTER scores among 3rd year students in Science taking 4 different majors (Math, Geosciences, Biology and Chemistry) using analysis of variance. A total sample size of 20 students (5 in each major) was studied. The Error Sum of Squares is SS Error = 64. What is the Mean Square Error (MSE )?
looking for an explanation 15) As part of a study at a large university, data were collected on 224 freshmen computer science 1 (CS) majors in a particular year. The researchers were interested in modeling y, a student's grade point average (GPA) after three semesters, as a function of the following independent variables (recorded at the time the students enrolled in the university): xi-average high school grade in mathematics (HSM) x2 = average high school grade in science (HSS) x3-...
For students who first enrolled in two year public institutions in a recent semester, the proportion who earned a bachelor's degree within six years was 0.389. The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate. (a) Determine the null and alternative hypotheses. (b) Explain what it would mean to make a Type I error. (c) Explain what it would mean to make a Type II error. (Type...
7. A survey of first-year and second-year students at a large university asked if students were satisfied with college life. We are interested in whether there is a difference between first and second-year students with respect to this question. You performed a hypothesis test and found there was no evidence of a difference between first and second-year students in response to this question. You based th on a test using alpha -0.01. Would you have made the same decision at...
