The admin of a web server is trying to get a sense of the average time delay for searches that require database queries. A random sample of 40 queries gives the following results (in milliseconds):

120, 213, 264, 48, 223, 228, 160, 162, 160, 140, 166, 133, 147, 200, 256, 189, 164, 139, 143, 348, 204, 165, 168, 225, 152, 105, 232, 132, 195, 137, 265, 166, 151, 164, 93, 122, 59, 112, 177, 167

Produce a 90%, 95%, and 99% confidence interval for this sample. You may, of course, use R for your calculations.
