A large sample of data (n = 335) from a Calgary observatory produced a mean daily counting

Question:

A large sample of data (n = 335) from a Calgary observatory produced a mean daily counting rate for cosmic rays of 3465.46, and a standard deviation of 127.72. Use these sample data to find the 90% confidence interval for the mean of the daily counting rates. Suppose a scientist claims that the mean of the daily counting rates is actually 3525. Would that claim be consistent with the confidence interval?
