In "commercial" the "ci" makes an "sh" sound. There are no actual silent letters, though. In "occasion" (note the spelling) the "si" makes a "zh" sound, but again, there aren't any silent letters.

What 4%? If you are talking about the difference between a CI of 95% and 99%, the latter is more likely to include the true mean. It depends on how much of a risk you want to take in terms of estimating the mean. Of course, the larger your n, the more accurate your estimate of...
