The accompanying data on families with 6 children are taken from the same study as the families with 12 children in Example 3.7.1. Fit a binomial distribution to the data. (Round the expected frequencies to one deci- mal place.) Compare with the results in Example 3.7.1. What features do the two data sets share?
NUMBER OF
BOYS GIRLS NUMBER OF FAMILIES
(a) Fit a binomial distribution to the observed data. (Round the expected frequencies to one decimal place.)
(b) Interpret the relationship between the observed and expected frequencies. Do the data cast suspicion on the classical assumption?
