<PRE><B>Question 560309</B>
400 people were observed entering the building. The number using each entrance is reported below. At the .01 significance level, is there a difference in the use of the four entrances?
Entrance:::::::::::observed:::expected
Main Street:::::::::: 140:::::::100
Broad Street::::::::: 120:::::::100
Cherry Street::::::::: 90:::::::100
Walnut Street::::::::: 50:::::::100

Ho: proportions are the same
Ha: proportions are not the same
I ran a Chi-Sq Goodness of Fit test and got the following:
X^2 = 46
p-value: 5.6715x10^-10
df: 3
====
Conclusion:
Since the p-value is less than 1% reject Ho.
The proportions are not all the same.
