A survey of several 10 to 11 year olds recorded the following amounts spent on a trip to the mall:
$17.33,$19.83,$21.10,$24.20,$13.72,$17.82
Construct the 95% confidence interval for the average amount spent by 10 to 11 year olds on a trip to the mall. Assume the population is approximately normal.
Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
