If the prevalence ratio includes the null value, then we cannot
rule out the null hypothesis that there is no relationship between
obesity and metabolic syndrome.
1. Use the table below to calculate the prevalence ratio
and chi-square statistic and calculate the
confidence interval for the prevalence ratio.
2. Does the confidence interval include the null value?

he true percentage of left-handed people is 13% (p = .13) a. If we survey two hundred people, how many left handers do you expect to survey? b. If you repeat this survey, will you always get this number of left-handers (the expectation)? Why or why not? c. What is the spread (standard deviation) of the sample proportions? d. Use the empirical rule to describe where we expect sample proportions to lie if we repeated this survey (with size of...

There is a bug sitting between the threads of your car tire. We start a short commute of 1 mile and the bug remains at the same location between the tread of your tire without getting squished. Assume the tire is 2 feet in diameter ( so the center is exactly 1 foot above the pavement ) and the thread width is negligible so the bug is almost touching the road as the tire rotates. 1. How far does the...
