Question

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?

Explanation / Answer

The expected frequency of Indians are: 44/(25+42+…+44)=0.183

The critical chi value is chi(6-1,0.05)=11.070
