Monthly rent paid by undergraduates and graduate students.

Undergraduate Student Rents (n = 10)
810	770	870	710	730
830	820	660	980	700

Graduate Student Rents (n = 12)
1,150	910	920	860	780	910
740	820	940	920	830	880

(a) Construct a 90 percent confidence interval for the difference of mean monthly rent paid by undergraduates and graduate students, using the assumption of unequal variances with Welch's formula for d.f. (Do not round the intermediate calculations. Round your final answers to 3 decimal places. Negative values should be indicated by a minus sign.)

The 90% confidence interval is from which number to which number?

A recent graduate moving to a new job collected a sample of the monthly rent (in dollars) and the size (in square feet) of 3-bedroom apartments in one area of a city. Use Excel to find the best fit linear regression equation, where size of the apartment is the explanatory variable. Round the slope and intercept to two decimal places.

In a study about undergraduate student credit card usage, it was reported that undergraduate students have a mean credit card balance of $3173 (Sallie Mae, April 2009). This figure was an all-time high and had increased 44% over the previous five years. Assume that a current study is being conducted to determine if it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the April 2009 report. Based on previous studies,...

8. Linear equations and the regression line Suppose a graduate student does a survey of undergraduate study habits on his university campus. He collects data on students who are in different years in college by asking them how many hours of course work they do for each class in a typical week. A sample of four students provides the following data on year in college and hours of course work per class: Student Year in College Course Work Hours per...

17. A campus program evenly enrolls undergraduate and graduate students. If a random sample of 4 students is selected from the program to be interviewed about the introduction of a new fast food outlet on the ground floor of the campus building, what distribution should be used to calculate the probability that 3 out of 4 students selected are undergraduate students? a. Binomial distribution b. Poisson distribution 18. Based on the information in question 17, please find the probability that...

A graduate student in the School of Education is interested in whether families of students in the Chicago Public Schools are for or against the new legislation proposing school uniform requirements. She surveys 600 students and finds that 480 are against the new legislation. Compute a 90 and 98 percent confidence interval for the true proportion who are for the new legislation.

A random sample of Penn State World Campus undergraduate and graduate students were contacted and data concerning their gender identities were recorded. In a random sample of 40 undergraduate students, 21 identified as men and 19 identified as women. In a random sample of 40 graduate students, 17 identified as men and 23 identified as women. [15 points] A. Is it appropriate to use the normal approximation method here to construct a confidence interval for the difference in population proportions? Show...

3. It is frequently difficult for graduate schools to compare students from different undergraduate programs since universities have vastly different scales of assessment. Some schools, for example, are known to in ate grades while others maintain more rigorous grading standards. Say that you are a graduate school admissions officer charged with selecting those applicants that have the best undergraduate grades relative to their peers. You must decide between two students - one from Princeton and one from Temple. The Princeton...

Scenario 8.2 The undergraduate grade point average (GPA) for students admitted to the top graduate business schools was 3.37. Assume this estimate was based on a sample of 90 students admitted to the top schools. Using past years' data, the population standard deviation can be assumed known as 0.30. 1. Based on the information in Scenario 8.2, you are to construct a 95% confidence interval estimate of the mean undergraduate GPA for students admitted to the top graduate business schools,...
