We are looking at the question to examine the relationship between gender and weapon of choice in domestic assault.
Question: Does female choose weapon differently than male during domestic assault?
Male Female Totals
Gun 93 37 130
Knife 27. 98 125
Others 24 26 50
Total 144 161 305
The null hypothesis is:
Ho: There is no difference between male and female in the choice of weapon during domestic assault.
1. Use Chi Square test to determine whether the Ho is supported or not. Use 95% confidence level and the Chi Square Table from the last week's assignment.
2. Use Lambda test to decide on the Ho.
