(a) Use Table 5 "Fifty randomly-selected second or subsequent births and Table 6 "Fifty randomly-selected first births for this part. Use hypothesis testing for independent data to decide whether there is sufficient evidence to conclude that average gestational ages are different for first-borns and subsequent births. Check this at two levels of significance: 0.1 and 0.01. (b) Use Table 7 "Fifty pairs matched for mother's ages for this part. The table provides data for 50 pairs of births where the mother's are age-matched but differ in whether this is the mother's first birth or a subsequent birth. Use hypothesis testing for dependent data to decide whether there is sufficient evidence to conclude that that average gestational age is greater for first-borns than for subsequent births. Check this at two levels of significance: 0.05 and 0.001.
