Question

Based upon your answers to 1A and 1C, specify whether you would reject the null hypothesis or would fail to reject the null hypothesis. Then explain what could be concluded about binge drinking based upon this result. 

1. A researcher expects that the number of people (18 years and older) who report binge drinking
in the past month will be higher for Appleton WI residents as compared to the national rate,
which is 25%. The researcher samples 100 residents from Appleton WI (age 18+) and finds that
36 of the 100 Appleton residents reported binge drinking in the past month. Using this data set
answer the following questions:
A. What is yobt?
Xobt^2 = 6.4533
B. What is the df for this test?
Df=1
C. What is x²cv?
The value of X^2cv is 3.8415.
There is sufficient evidence to support the claim that the number of people who report binge
drinking in the past month will be higher for Appleton WI residents as compared to the national
rate, which is 25%.
