According to a survey, 21% of residents of a country 25 years old or older had earned at least a bachelor's degree. You are performing a study and would like at least 10 people in the study to have eamed at least a bachelor's degree. (a) How many residents of the country 25 years old or older do you expect to randomly select? (b) How many residents of the country 25 years old or older do you have to randomly select to have a probability 0.90 that the sample contains at least 10 who have earned at least a bachelor's degree? (a) The number of randomly selected residents is 48. (Round up to the nearest integer.)

According to a survey, 21% of residents of a country 25 years old or older had earned at least a bachelor's degree. You are performing a study and would like at least 10 people in the study to have earned at least a bachelor's degree.
(a) How many residents of the country 25 years old or older do you expect to randomly select?
(b) How many residents of the country 25 years old or older do you have to randomly select to have a probability 0.90 that the sample contains at least 10 who have earned at least a bachelor's degree?
(a) The number of randomly selected residents is 48. (Round up to the nearest integer.)
(b) The number of randomly selected residents, with a probability 0.90 containing at least 10 who have earned at least a bachelor's degree, is [ ]. (Round up to the nearest integer.)
