Question 1044815
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)
The margin of error is +/-3.7
The best answer is A, because it deals with population mean commute time, which is a more precise statement than the commute time.  It is not a probabilistic statement, so B and C are eliminated.
