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 745 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.

Transcribed Image Text: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. 56 of the 745 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 745 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.
