A psychologist is interested in constructing a 90% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. 57 of the 712 randomly selected people who were surveyed agreed with this theory. Round answers to 4 decimal places where possible.

a. With 90% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is between _______ and _______.

b. If many groups of 712 randomly selected people are surveyed, then a different confidence interval would be produced from each group.

About _______ percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain and about ______ percent will not contain the true population proportion.
