Suppose you are trying to show that there is a relationship between gender, living arrangement and the number of texts sent daily among students.

Prompt: Suppose you are trying to show that there is a relationship between gender, living arrangement and the number of texts sent daily among students. You take a sample of 12 students, record their gender (F&M) and ask whether they live at home (H), campus (C), or off campus (O)

	H	C	O
F	3 & 7	9 & 13	12 & 16
M	1& 5	3 & 7	2 & 6

Questions: (Known top row effect = +3, sum of square total =244)

1. What is the sum of squares interaction? (correct answer is 32)

2. What is the mean square for the row variable? (correct answer is 108)

Expert Solution

Hence

SS interaction = SS r*c = 32

2)

MS for row = 108

5. The number of daily texts sent by Marymount students are normally distributed with a mean of 80 texts and a standard deviation of 50 texts. (a) Find the probability that a randomly selected Marymount student sends more than 100 texts each day. (b) Find the probability that 25 randomly selected Marymount students will have a mean number of daily texts sent that is greater than 50 texts. (c) Suppose a parent wants their child in the bottom 25% of...

A statistics student wondered whether there might be a relationship between gender andcommuting methods among students at a high school. He surveyed 200 the high school students (92 males and 108 females) he happened to encounter around campus, asking each of them about their typical way of commuting to the college. The data from this survey appears below: Male Female Car 56 37 Bus 30 48 Neither 6 23 1. List the appropriate conditions for this test and explain why...

You conducted a study on the relationship between alcohol consumption and depression among college students in which you distributed a survey to 300 college seniors. Students who completed the survey responded to a standardized questionnaire measuring depression symptoms and to a series of questions about their typical alcohol consumption patterns. The results of your study indicated that the correlation between depression and alcohol consumption was +.34. Explain what this correlation means in terms of direction and strength. One possible explanation...

Researchers were interested in the relationship between mental health and living with a pet. Students were surveyed and grouped by pet type as either “Cats”, “Dogs”, or “No Pets”, and completed a scale on depressive symptoms on a scale of 1-7, where 7 indicates high levels of depressive symptoms. Using the data in the frequency table below, please conduct a one-way ANOVA to determine if there are any significant differences between these groups. Use α = .05, report η², and...

The following table shows the daily relationship between the number of workers and output (Q) for a small factory in the short run, with capital held constant. Each worker costs $200 per day, and the firm has fixed costs of $100 per day. Calculate total cost (TC), marginal cost (MC), and average total cost (ATC). (Round your answers to two decimal places.) WORKERS Q TC MC ATC 1 20 ? ? ? 2 44 ? ? ? 3 70...

You are interested in the relationship, if any, between reward and gender on the productivity of your employees. To test your suspicion that the variables are independent, you divide 100 employees into two groups of 50 males and 50 females. After each member of either group is rewarded, you record their change in productivity with the following results: Productivity Decreases No Change Increases Males 30 15 5 Females 20 15 15 What is the critical value at the .05 level of significance?...
