Homework SourseAre shoppers at Macys equally represented from the six major
Are shoppers at Macy\'s equally represented from the six major ethnic demographics? See the below table. Test the null hypothesis, that admittance rates are distributed equally throughout the state, at the .05 level of significance.
Race | Number of Shoppers
White | 25
Black | 42
Asian | 40
Spanish | 43
Greek | 46
Indian | 44
What is the expected frequency of Indians?
What is the critical chi-square value?
What value of chi-square did you compute?
Do you accept or reject the null hypothesis?

Solution
The expected frequency of Indians are: 44/(25+42+…+44)=0.183
The critical chi value is chi(6-1,0.05)=11.070
