A curious high school student has asked for help interpreting data they found on how many licks it takes to reach the Tootsie Roll center of a Tootsie Pop. From a sample of 33 hungry high school students, you find the average number of licks is 268. The reported standard deviation is 14 licks. For a 90% confidence level, what is the upper bound in number of licks of the confidence interval to reach the Tootsie Roll center of a Tootsie Pop? Round your answer to 1 decimal place for entry into Canvas. Do not enter units. Example: 123.4
