Homework Answers
The fine motor development of a child starts in about 3 months where a child can grasp things but cannot hold.This holding develops at the age of 12 months where the child can hold the object with good grip.So a child can hold the breast while breastfed by the mother. Hence it 8s associated with one another.
A dependent variable is one which can be measured .Here the child's activity like "holding" can be measured in accordance to age.The breastfeeding is the independent variable.

You conduct a case-control study in Portland pediatric clinics to evaluate the relationship between the exposure of exclusive breastfeeding for at least the first 6 months of life, and the outcome of no ear infections during the first year of life. The exposure is “exclusive breastfeeding” (as opposed to mixed feeding or formula feeding. The outcome of interest is “no ear infections during the first year of life” (as opposed to having at least one ear infection). Your study produces...

5. (10 points) Acute rotavirus diarrhea is the leading cause of death among children under age 5, killing an estimated 4.5 million annually in developing countries. Scientists from Finland and Belgium claim that a new oral vaccine is 80% effective against rotavirus diarrhea. a) What is the probability distribution of the random variable X, the number of effective cases out of 1500 cases? b) What is the probability that the vaccine will be effective in less than 1225 cases? c)...

2. In another vaccination study, the incidence of chicken pox among non-vaccinated children, younger than 12, was found to be 200/1,000 and the incidence among the vaccinated was 101,000. From another source we know that 30% of the total population (under 12 years of age) was not vaccinated, calculate the following for the given data: (a) The incidence of chicken pox attributable to non-vaccination of the total (under 12) (2 pts) (b) The proportion of the risk of chicken pox...
