The Centers for Disease Control and Prevention reported a survey of randomly selected Americans age 65 and older, which found that 535 of 1068 women and 421 of 1012 men suffered from some form of arthritis. Is this evidence that women are more likely to suffer from arthritis then men? Test an appropriate hypothesis using a significance level of 0.10 ( = 0.10). You can assume all conditions and assumptions are met.
