Question
A survey of u.s adults found that 65%?would want their organs transplanted into a patient who needs them if they were killed in an accident. You randomly select 110 adults and ask each if he or she would want their organs transplanted into a patient who needs them if they were killed in an accident. Estimate the probability that at least 70 people say yes? A survey of u.s adults found that 65%?would want their organs transplanted into a patient who needs them if they were killed in an accident. You randomly select 110 adults and ask each if he or she would want their organs transplanted into a patient who needs them if they were killed in an accident. Estimate the probability that at least 70 people say yes?Explanation / Answer
Compute 1-proportion Z test to find the probability.
Z=(Ps-Pu)/sqrt [Pu(1-Pu)/N], where, Ps and Pu refer to sample and population proportion, N efer to ample size.
Z=(70/110-0.65) sqrt [0.65(1-0.65)/110]
=-0.30
The required probability is 0.3821.
