In a study of binge drinking among undergraduates at Ohio University, a researcher was interested in gender differences as related to binge drinking and to drinking-related arrests. She wanted to know two things: (a) Is there a significant relationship between gender and binge drinking (as defined by 5 or more drinks at one sitting), and (b) Is there a significant relationship between gender and drinking-related arrests? A random sample of males and females were asked about their experiences with binge drinking and with drinking-related arrests.
A.Use the numbers below for this question only!
Binge Drinking?
YES NO
Male 243 280
Female 214 264
What would the expected value for the "male-yes" cell be?
B. Use the numbers below for this question only!
Binge
Drinking?
YES NO
Male 252 244
Female 211 259
What would the expected value for the "female-no" cell
be?

A study conducted at a major university indicates that the
tendency among undergraduates to seek the assistance of helper
differs by ethnic group. You select 25 subjects each from two
different ethnic groups or business majors and count the number who
sought help. In ethic group A, 11 sought out helpers at some point.
In ethnic group B, 17.
What are the frequency expected values for each group?
Do results support the earlier study?
What does the alternate hypothesis suggest...

3. A national study has shown that 44% of college students
engage in binge drinking (5 drinks at one sitting for men, 4 for
women). Assume that the 53 students taking Stat 216 this summer
represent a random sample of college students in the US.
(a) Define the parameter of interest and what symbol you would
use to represent it.
(b) Show whether or not the conditions are met for us to apply
the CLT here.
(c) Assuming the conditions...

1. A stress level study based on a random sample of 49
undergraduates at your university reported a mean of 73 (on a 0-100
scale). Assume the population standard deviation is 28.
(a) Find the margin of error for an 80%, 90%, 95%, and 99%
confidence interval. Draw a diagram with the confidence intervals,
and summarize the effect of the confidence level on the margin of
error.
(b) Now consider changing the sample size, but assume that the
sample mean...
