Answer:
Step-by-step explanation:
The confidence interval for population proportion(p) is given by :-
, where = Sample proportion.
n= Sample size.
z* = Critical value.
Let p = Proportion of adults in the U.S. who have donated blood in the past two years.
As per given , we have
n= 2322
Sample proportion of adults in the U.S. who have donated blood in the past two years. :
By z-table , the critical value for 90% confidence : z*= 1.645
Then, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years will be
Hence, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years. =
