Suppose a random sample of 15 college students indicates that
the group spent an average of $1362 on books and supplies for the
Spring semester of 2022. The sample standard deviation is $102.
Find a 90% confidence interval for the cost of books and supplies
for all college students this semester. You may assume that all
validity conditions are met. Give an interpretation of your
confidence interval.
