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
