A sample of 120 families with 4 children each in which both parents are carriers of an autosomal recessive mutation for cystic fibrosis produces the following distribution of children with and without cystic fibrosis. 16 families with 0 children with CF and 4 children without CF 52 families with 1 children with CF and 3 children without CF 32 families with 2 children with CF and 2 children without CF 18 families with 3 children with CF and 1 children without CF 2 families with 4 children with CF and 0 children without CF Is the distribution of families with 0 to 4 children with CF consistent with ratios expected under the binomial probability? Support your answer with a statistical value.
