I don't get Assignment 5
1.4
when did we ever talk about z score conversion?
also is this okay for number 5?
5.
H(0): The crime rate is independent of outdoor temperature.
H(1): The crime rate is dependent on the outdoor temperature.
X2 obtained = 29.26
alpha level =.05
Df = 4
X2 critical = 9.49
Decision: reject the null, the crime rate is dependent on the outdoor temperature.
it doesn't make sense that temperature can affect crime rate. I might be doing something wrong. Anyone?
