Mean ounces = (14.5+14.6+14.7+14.8+14.9+15.5+14.8+15.2+15+15.1+15+14.4+15.8+14+16+16.1+15.8+14.5+14.1+14.2+14+14.9+14.7+14.5+14.6+14.8+14.8+14.6)/30
Sorting the dataset, the following is obtained:
14  14   14.1   14.2   14.4   14.5   14.5   14.5   14.6   14.6   14.6   14.7 14.7   14.8   14.8   14.8   14.8   14.9   14.9   14.9   15   15   15.1   15.2 15.3  15.5   15.8   15.8   16   16.1
Hence, median = (15-th data + 16-th data)/2 = (14.8+14.8)/2 = 14.8
Standard deviation = 8.78330 ≈0.54 ounce
