Office workers complain that the noise level in their office Area 1 is greater than that in the company's other office Area 2. Six measurements are made on different days in each area, with the following results:
Area 1: 61, 66, 65, 72, 59, 68 decibels
Area 2: 64, 56, 53, 61, 63, 51 decibels
(a) Can the workers of Area 1 legitimately conclude that their Area 1 is noisier?
(b) Is the noise level of Area 1 greater than 60 decibels?
