In a survey, 25 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $39.4 and standard deviation of $7.2. Estimate how much a typical parent would spend on their child's birthday gift (use a 80% confidence level). Give your answers to 3 decimal places. Express your answer in the format of ¯xx¯ ±±  E.  $ ±± $
