Part One: Complete
problems 4.32a,
4.46c, 5.4, 5.18, 5.28, 5.35ab in the textbook.
Hint for 4.46c: read the problem
statement as “Given a person used a mobile phone, what is the
proportion that i) had eye cancer ii) did not have eye cancer.”
Also, the column labeled case refers to people who had cancer and the
column labeled control refers to people who did not have cancer.
Part Two: Answer the following
question:
A Gallup Organization poll conducted in
July 2003 reported the results of a survey asking approximately 1000
randomly chosen Americans questions about fast food consumption.
It reported that 59% of the respondents eat fast food at least once
weekly. What is the margin of error of the Gallup Organization poll?
Barring any major incidents that could change people’s minds,
between what two numbers can we be confident that true proportion of
respondents eat fast food at least once weekly lies?
