Each year, Hudson's Bay Company, sets up a gift-wrapping station to assist its customers with holiday shopping. Preliminary observations of one worker at the station produced the following sample time (in minutes per package): 3.4,3.3,4.1,3.7,3.9. Assume a 99% confidence level and an accuracy of 5%. Based on this small sample and the given confidence level and accuracy level, the number of observations that would be necessary to determine the true cycle time is observations (round your response up to the next whole number)
