Question 188610
 I am just really having a problem with this... 
A store manager believes that 25% of their customers come in on Monday, 15% on
Tuesday, 15% on Wednesday, 15% on Thursday, and 30% on Friday. Test at the .01
level if the manager is correct if one week the following number of customers
came in to the store. 
Monday: 32 Customers
Tuesday: 15 customers
Wednesday: 17 customers
Thursday: 16 customrs
Friday" 40 customers
------------------------------------ 
Find the critical value. 
Use the Chi-Sq table with df = 4 and right tail = 1%
Ans: A. 13.277
------------------------- 
Perform a Chi-Sq calculation:
Observed values are 32/120,15/120,17/120,16/120,40/120
Expected values are the percentages listed.
Ho: All the percentages are correct
Ha: At least one of the percentages is not as expected.
--------------------------------
Find the test statistic. 

Ans: B. 0.13
