The given data is, the survey of 2299 adults in a certain country aged 18 and older conducted by a reputable polling organization found that 413 have donated blood in the past 2yesrs. So, x=413 and n=2299 a) The point estimate for the population proportion of adults in the country aged 18 and older who donated blood in the past 2 years is, p^=xn=4132299=0.180 The point estimate for the population proportion of adults in the country aged 18 and older who donated blood in the past 2 years is 0.180b) The sample can be assumed to be a simple random sample and the value of n*p^*(1-p^)=2299*0.180*(1-0.180)=339.332 which is greater than 10 and the sample size can be assumed to less than or equal to 5% of the population size.c) The 90% confidence interval for the population proportion of adults in the country who have donated blood in the past 2 years is, Confidence interval =p^ ±Zα/2*p^(1-p^)n = (0.180 ± 1.64 *0.180*(1-0.180)/2299 =(0.167, 0.193) We are 90% confident the proportion of adults in the country aged 18 and older who have donated blood in the past 2years is between 0.167 and 0.193.
