A teacher wants to estimate the mean time (in minutes) that students take to go from one classroom to the next. His research assistant uses the sample time of 35 students to report the confidence interval as [9.30, 10.70].

Determine the confidence level if the sample standard deviation used for the interval is 2.449.

Note: Round your final answer to the nearest whole number.
