H0: p1=p2

(Two tailed test at99%)
Difference 14.44 %
Chi-squared 5.883
DF 1
Significance level P = 0.0153
Since p >0.01, our alpha reject null hypothesis.
NO. Based on the sample results, you can not conclude that there is a higher proportion of companies offering high-deductible health insurance plans to their workers in 2007 than in 2006
