A random sample of 35 customers has an average order size of $80, and a population standard deviation of $22.00. Not all samples of this size would give you the same sample average, so you'd like to construct an "interval estimate" to convey this uncertainty. What is a 90% confidence interval for this mean? a $78.97 - $81.03 b $43.81 - $116.19 c $73.88 - $86.12 d $72.56 - $87.44

Several years ago, 45% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,025 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,025 surveyed, 484 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed.

Students who graduated from college in 2010 owed an average of $25,250 in student loans (The New York Times, November 2, 2011). An economist wants to determine if average debt has changed. She takes a sample of 40 recent graduates and finds that their average debt was $27,500 with a standard deviation of $9,120. Use the 90% confidence interval to determine if average debt has changed.
