Statistical Significance from confidence interval

[frozen]

Q1. A modelA incorrectly classifies 5 records out of 100 records.

 modelB incorrectly classifies 3 out 100 records. for the same data.  Is it better than the first one with statistical significance at 90% confidence level?

(

I used Binomial distribution and found out these confidence intervals:

*model A:  (0.9141, 0.9859)

*modelB:( 0.942, 0.998)

)

 

Q2.  In the image below why 2nd one is not significant ?
