Question 1044974
98% CI is mean +/- t(0.99, df=22)s/sqrt(n)
34.4+/- 2.508*7.1/sqrt(23); the second part equals 3.7
(30.7,38.1) is the 98% CI.
The margin of error is +/-3.7
It says statistically that the true mean of the population is somewhere between 30.7 and 38.1 with high confidence.  We don't know exactly where it is, but we are very confident the interval contains it. The non-statistical interpretation is that the commute time is fairly predictable given that margin of error.

Note, there is not a probability statement here.  The true mean, the parameter, either is or isn't in the interval. That isn't a probabilistic statement.  Nor is there a confidence interval for the sample.  We are completely confident in the sample itself.
