Question

in an effort to more clearly understand global needs for dental health education, the World Health Organization requested information from a sample of citizens in each of the countries below. individuals were asked to categorize the adequacy of their dental health care, according to pre-determined criteria. the table below includes the results of the study.

United kingdom: adequate health care: 2,539 Inadequate health care: 176

United states: adequate health care: 4,563 Inadequate health care: 209

France: adequate health care: 1,298 Inadequate health care: 307

Mexico: adequate health care: 2,874 Inadequate health care: 266

What is the probability that a patient from the united states has adequate dental care?

What proportion of children have adequate dental care?

What proportion of children with inadequate dental care are from the united states?

What is the probability that a child from France has inadequate dental care?

Answer 1

a) Probability that a patient from the united states has adequate dental care is computed here as:

= Number of adequate dental care from United States / Total from US

= 4563 / (4563 + 209)

= 0.9562

Therefore 0.9562 is the required probability here.

b) The proportion here is computed as:

= Total Adequate dental care children / Total children

= (2539 + 4563 + 1298 + 2874)/(2539 + 4563 + 1298 + 2874 + 209 + 176 + 307 + 266)

= 11274 / 12232

= 0.9217

Therefore 0.9217 is the required proportion here.

c) The proportion of children with inadequate dental care that are from the united states is computed here as:

= 209 / (209 + 176 + 307 + 266)

= 0.2182

Therefore 0.2182 is the required proportion here.

d) The probability that a child from France has inadequate dental care is computed here as:

= 307 / (307 + 1298)

= 0.1913

Therefore 0.1913 is the required probability here.
