According to a popular wedding magazine, the mean cost of flowers for a wedding is $750. Recently, in a random sample of 45 weddings in the US it was found that the average cost of the flowers was $734, with a standard deviation of $102. On the basis of this, a 90% confidence interval for the mean cost of flowers for a wedding is $701 to $767. Choose the statement that is the best interpretation of the confidence interval. Select...
