Question 2: The birth weights (kgs) of 36 babies born after normal pregnancies of 40 weeks were:

3.5 4.1 2.8 3.2 2.8 3.1 3.4 3.0 2.3

3.8 2.7 3.7 3.9 2.6 2.7 3.1 2.2 2.9

3.2 3.7 3.3 4.3 3.4 3.5 4.6 3.1 3.4

3.5 3.5 3.8 2.4 3.0 3.6 4.0 2.9 3.3

Is the mean weight of babies born after a normal pregnancy 3.6kgs? The standard deviation is assumed known and is 0.6kgs.
