Impact of College Roommates on Grades In this exercise, we investigate answers to the questions: How much of an effect does your roommate have on your grades? In particular, does it matter whether your roommate brings a videogame to college? A study was conducted involving n = 210 first-year students who were randomly assigned a roommate. Table 1 gives summary statistics on grade point average (GPA) for the first semester depending on whether the student and/or the roommate brought a videogame to campus. Student brought videogame No The 99% confidence interval is i Yes No Yes Roommate brought videogame -0.008 No No Yes Yes Sample size Mean GPA 88 44 38 40 3.128 to i 0.578 3.039 2.932 2.754 St. Dev. 0.590 Table 1 Videogames and GPA Considering only students who do bring a videogame to campus, find a 99% confidence interval for the difference in mean GPA between students whose roommate does not bring a videogame and those whose roomate does bring a videogame μN - μy, where μN represents the mean GPA for students whose roommate does not bring a videogame and μy represents the mean GPA for students whose roommate does bring a videogame.

I need help with just part c. Someone on here already answered it for me but I'm really confused as there are steps missing and I'm not sure what to put in the calculator. " The first quartile separates the lowest 25% of the observations from the higher 75% of the observations. The first quartile is denoted by Q1. The second quartile separates the lower 50% of the observations from the higher 50% of the observations. The second quartile is denoted by Q2.The second quartile is same as median. The third quartile separates the lowest 75% of the observations from the higher 25% of the observations. The third quartile is denoted by Q3. The third quartile can obtained as follows...."

Several years ago, the Arcadia school system was criticized because the average Arcadia High School graduate could read at only the ninth-grade level. After this report was made, a special reading program was established to upgrade skills. The AHS principal wants to know if the reading program worked. If it has, he will request that an accreditation team visit the school. If the program has not improved the reading level to at least 10.0 (sophomore level), the administrator would like to avoid the embarrassment of a poor review. To determine the average reading level of the senior class, we select ten seniors at random. We assume that reading scores are normally distributed. The reading scores for the ten seniors are shown in Table 1. Table 1: Reading Scores for Sample High School Seniors Student Reading Score 1 13.4 2 12.1 3 11.4 4 10.6 5 10.3 6 10.2 7 9.8 8 9.7 9 9.4 10 8.6 Calculate the sample mean…

For one month, 500 elementary students kept a daily record of the hours they spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school tended to spend less time watching television than those students who did poorly. Listed are several possible statements concerning the results of this research. Place a check by every statement that you agree with based on this study. a. Even though students who did well watched less television, this doesn't necessarily mean that watching television hurts school performance. b. One month is not a long enough period of time to estimate how many hours the students really spend watching television. c. The sample of 500 is too small to permit drawing conclusions about elementary students in general. d. I don't agree with any of these statements. e. If a student decreased the…

Please help needed on this asap. Thanks so much! It has been observed that some persons who suffer colitis, again suffer colitis within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 170 people in the first group and this group will be administered the new drug. There are 132 people in the second group and this group wil be administered a placebo. After one year, 14% of the first group has a second episode and 18% of the second group has a second episode. What is a 90% confidence interval for the difference in true proportion of the two groups.
