We would like to test if students who are in Electrical Engineering, Mechanical Engineering and Computer Engineering spend the same amount of time studying outside of class. Representative samples are collected and descriptive statistics are performed. What type of statistical test should we use? Explain.
Homework Answers
We need to compare the mean amount of time studying for three groups. Hence,
We should use One Way ANOVA.

A professor hypothesizes that students who earn a C or better in her class spend more time outside of class studying than students who receive a D or F. She collects the following data from two samples of students. What does she conclude? Number of hours studying per week for C or better students: 8, 4, 4, 2, 1, 5, 3, 2, 3 Number of hours studying per week for D or F students: 6, 2, 1, 0, 3, 2,...

Mean entry-level salaries for college graduates with mechanical engineering degrees and electrical engineering degrees are believed to be approximately the same. A recruiting office thinks that the mean mechanical engineering salary is actually lower than the mean electrical engineering salary. The recruiting office randomly surveys 42 entry level mechanical engineers and 54 entry level electrical engineers. Their mean salaries were $46,000 and $46,900, respectively. Their standard deviations were $3450 and $4210, respectively. Conduct a hypothesis test at the 5% level...

Suppose that a very large population of students has taken this same test on the internet. Their mean score was 7 and their population standard deviation was 4. Assume that there are 49 students in our statistics class and that these students can be thought of as a random sample from the same large population of students who took the statistics quiz online. Suppose that the mean quiz score for our class is 9. Now imagine that we draw many...

Problem 3 (Frequency Response Testing) A common application for Fourier in mechanical design relates to the concept of resonance that we discussed earlier in the semester. Recall that resonance occurs when you drive a mechanical or electrical system at or near its natural frequency, whích then causes large amplitude oscillations. For relatively simple systems...

Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem. Include the null and alternative hypothesis, alpha value, p-value, and a conclusion. Make sure that you use appropriate terminology, specify whether you are using the classical method or the p-value method, and fully explain your solution. How do we determine that we are to fail to reject the null hypothesis? What process do...

It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test the hypothesis that students who study one week before score different from students who study the night before. A hypothesis test for two independent samples is run based on your data and a p-value is...

In the United States, Scholastic Aptitude Test (SAT) scores are used by universities when selecting students for admission. Private companies and high schools offer SAT preparatory courses to help students improve their scores. This has led some people to ask, "Do SAT preparatory classes effectively increase SAT scores?" The following study, cited in a major newspaper, claims that they do (but not by a substantial amount): "A new study . . . shows that [SAT preparatory] classes are effective in...

1. A mathematics professor believes that the performance of students taking an elementary calculus course has declined in recent years. The professor decides to reuse a final exam that was first administered 10 years ago. At that time the mean score was 81 with s=10, for the 50 students in the section taught by that professor When given to the current class of 53 students, who observed essentially the same set of lectures, the mean is 75 with s=15. If...
