   Question

   The table below describes data from a survey held at a museum.

   Are gender and type of job at this museum independent of each other? Test with alpha = .05.

   
   
   1. FALSE: Yes, because the observed chi-squared is larger than the critical chi-squared.
   2. TRUE: Yes, because the observed chi-square is smaller than the critical chi-square. .
   
   

   Solution

   The critical value can be found in the table. The observed value can be calculated with:

   f₀ is the observed number en f_e is the expected number. r = row and c = column.

   
   
   1. False
   2. True
