A TA in statistics thinks that the format of the conferences and the timing of the assignments may affect students'assignment marks (out of 10). He decided to design three conferences with a different format: (1) with lecturing, (2) withdemonstrating problems, and (3) with involving students in active problem-solving. Twelve students attended one of theconferences (four in each format) and asked to submit their assignments at week 3. Another twelve students attendedone of the conferences but asked to submit their assignments at week 5. The data are tabled below:Assignment Week 3Week 5Lecture6,7,5,75,5,4,5FormatDemo problems7,8,8,96,7,7,6Active problems9,10,10,108,9,9,10Note: ΣΣΣx=1385Perform the ANOVA test and table the results, stating all critical values. State and explain what should be the follow-upanalysis after the overall F-test if any (NO calculation but just explain).

Here, we have to perform ANOVA test and then conclude results from the test.

5. In recent years there has been a great deal of research demonstrating gender discrimination in science, technology, engineering and math (STEM) fields. In one experiment, for example, faculty members viewed an application for a laboratory manager position. The applications were identical except that half had a traditionally male name (John) and half had a traditionally female name (Jennifer). In addition, half of the faculty participants were from STEM fields and half were from non-STEM fields. The faculty were asked to rate the competence of the applicants on a 6-point scale, with 1 indicating a lower rating. Group means are presented below, along with an incomplete summary table. After completing the table, write a conclusion about the outcome of the experiment.

A graduating senior has been accepted by three universities for an M.S. in engineering. Two criteria have been identified. The first is the program and university’s academic ranking. The second is the cost. A third criteria of location was initially considered, but then the student recognized that it is only for about a year, and applications were only made to acceptable schools. The student is currently enrolled in the first university, which is rated as a 5 for academic rank and a 7 for cost. The second is a larger outof-state public university, which is rated as a 7 for academic rank and a 6 for cost. The third is a prestigious private school, which is rated as a 10 academically and a 3 for its higher cost. (a) What is the total score for each school if the academic rank has a weight of 40%? (b) If academic rank has a weight of 60%, what is the total score for each school?

A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12
Prof. Flores, always interested in improving her teaching effectiveness, has decided to undertake a careful analysis of her evaluations from the past three years. A matter of special concern to her is how she is viewed by students of different majors. She's decided to look at the last question on the teacher evaluation form, Question 17, which is, "Would you recommend this professor to another student?" Each of Prof. Flores' students can be placed into one of three categories according to the student's major school, as shown in the contingency table below. (Students who have majors from more than one school are not included.) This table contains a summary of the data that Prof. Flores has collected for 500 of her students. Each of the 500 students is classified according to two variables: major school ("School of Social Science", "School of Engineering", or "School of Physical Sciences") and response to Question 17 ("No", "Maybe", or "Yes"). In the cells of the table are written the…
Throughout the world, women are targets of harassment, discrimination, violence, and evenmurder due to perceptions of their clothing choices. Some women are targeted because theydress to religious and some women are targeted because they do not dress religious enough. Aresearcher was interested in determining if countries that had more restrictions on how womendress (i.e., how many laws regulate women’s clothing choices?) also had more women reportingsocial hostility from others (e.g., discrimination, abuse, violence). What statistical test should beused to determine if there is a relationship between number of women’s clothing regulations andthe number of reports of social hostility? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B. What would be the appropriate statistical test? Explain your rationale.
Suppose you are a basketball coach and you've taken some measures on your starting five players. The two measures that you're most interested in right now are scores on a two-minute jump shot test (x) and time in seconds on a shuttle run (y). You want to determine a couple of things:1) On which variable (jump shots or shuttle run time) are your starters more consistent? 2) For player #1, is she a faster runner or better at jump shots? 3) For player #4, is she a faster runner or better at jump shots?

Two ad agencies want to understand issues that are important to students. Agency A will interview 50 students whose names are randomly chosen from school enrollment data. Agency B will interview 50 randomly selected people from those who respond to a social media posting. Which method will produce a fair sample of the student population and why? Agency A, because students are convenient and easy to interview Agency A, because names randomly selected from school data will be student names Agency B, because people who respond to social media postings have strong opinions Agency B, because people who respond to social media postings are usually students
In Spetember of 2013, Mario The Baker introduced a new chocolate cake and hired Doug and Jeremy to bake these cakes. Every customer buying this new chocolate cake either gives it a "thumbs up" or a "thumbs down". Based on the data accumulated between 10/2013 and 9/2014, we know that 40% of the cakes baked by Doug gets a "thumbs up", while only 10% of those baked by Jeremy gets a "thumbs up". About 70% of the cakes are baked by Doug. One cake was selected at random on 10/01/2014. Find the probability that the cake got a "thumbs up".
