Let s be the subset of the set of ordered pairs of integers defined recursively by basis step is (0, 0)∈ s recursive step: if (a, b) ∈ s, then (a, b+1) ∈ s, (a+1, b+1) ∈ s, and (a+2, b+1) ∈ s what is the list of the elements of s produced by the first four applications of the recursive definition?

The birth weights of newborn babies in the unites states follow in a normal distrubution with a mean of 3.4 kg and standard deviation of 0.6 kg. reaserches interested in studying how. children gain weights decide to take random samples of 100 newborn babies and calculate the sample mean birth weights for each sample
