Which of the null-hypothesis can be rejected at 95% confidence?

Consider the first 25 observations on Food Security for Cash Croppers with the corresponding information on CALREQ, ZHANEW, ZWANEW, and ZWHNEW. The variable “obs” in the first column is just a variable that 

tracks each observation in the sample data, where each unit of observation

is a typical respondent in the survey. Use the commands in STATA to check

for cross-tabulations and the Pearson chi-square tests between (1) Cashcrop

and insecure, (2) Cashcrop and CALREQ, (3) Cashcrop and ZWANEW and

finally, (4) Cashcrop and ZWNHEW. Which of the null-hypothesis can be

rejected at 95% confidence?
